An error path was missed though, that still takes\ndiscipline_mutex and thus has the original deadlock potential.\r\n\r\nIntermittent deadlocks were seen when a qeth channel path is configured\noffline, causing a race between qeth_do_reset and ccwgroup_remove.\nCall qeth_set_offline() directly in the qeth_do_reset() error case and\nthen a new variant of ccwgroup_set_offline(), without taking\ndiscipline_mutex.(CVE-2021-47382)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nNFSD: Fix the behavior of READ near OFFSET_MAX\r\n\r\nDan Aloni reports:\n\u0026gt; Due to commit 8cfb9015280d (\u0026quot;NFS: Always provide aligned buffers to\n\u0026gt; the RPC read layers\u0026quot;) on the client, a read of 0xfff is aligned up\n\u0026gt; to server rsize of 0x1000.\n\u0026gt;\n\u0026gt; As a result, in a test where the server has a file of size\n\u0026gt; 0x7fffffffffffffff, and the client tries to read from the offset\n\u0026gt; 0x7ffffffffffff000, the read causes loff_t overflow in the server\n\u0026gt; and it returns an NFS code of EINVAL to the client. The client as\n\u0026gt; a result indefinitely retries the request.\r\n\r\nThe Linux NFS client does not handle NFS?ERR_INVAL, even though all\nNFS specifications permit servers to return that status code for a\nREAD.\r\n\r\nInstead of NFS?ERR_INVAL, have out-of-range READ requests succeed\nand return a short result. Set the EOF flag in the result to prevent\nthe client from retrying the READ request. This behavior appears to\nbe consistent with Solaris NFS servers.\r\n\r\nNote that NFSv3 and NFSv4 use u64 offset values on the wire. These\nmust be converted to loff_t internally before use -- an implicit\ntype cast is not adequate for this purpose. Otherwise VFS checks\nagainst sb-\u0026gt;s_maxbytes do not work properly.(CVE-2022-48827)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nnet: can: j1939: enhanced error handling for tightly received RTS messages in xtp_rx_rts_session_new\r\n\r\nThis patch enhances error handling in scenarios with RTS (Request to\nSend) messages arriving closely.

In this case, the USB transfer must still\nbe shorter than dwNtbInMaxSize or dwNtbOutMaxSize. If\nexactly dwNtbInMaxSize or dwNtbOutMaxSize bytes are sent,\nand the size is a multiple of wMaxPacketSize for the\ngiven pipe, then no ZLP shall be sent.\r\n\r\nwBlockLength= 0x0000 must be used with extreme care, because\nof the possibility that the host and device may get out of\nsync, and because of test issues.\r\n\r\nwBlockLength = 0x0000 allows the sender to reduce latency by\nstarting to send a very large NTB, and then shortening it when\nthe sender discovers that there\u2019s not sufficient data to justify\nsending a large NTB\u0026quot;\r\n\r\nHowever, there is a potential issue with the current implementation,\nas it checks for the occurrence of multiple NTBs in a single\ngiveback by verifying if the leftover bytes to be processed is zero\nor not. If the block length reads zero, we would process the same\nNTB infintely because the leftover bytes is never zero and it leads\nto a crash. Fix this by bailing out if block length reads zero.(CVE-2024-35825)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm: vc4: Fix possible null pointer dereference\r\n\r\nIn vc4_hdmi_audio_init() of_get_address() may return\nNULL which is later dereferenced.

To address this, move the lock to struct\nstmmac_priv. We also need to reacquire the mutex lock when doing\nthis initialization.\r\n\r\nDEBUG_LOCKS_WARN_ON(lock-\u0026gt;magic != lock)\nWARNING: CPU: 3 PID: 505 at kernel/locking/mutex.c:587 __mutex_lock+0xd84/0x1068\n Modules linked in:\n CPU: 3 PID: 505 Comm: tc Not tainted 6.9.0-rc6-00053-g0106679839f7-dirty #29\n Hardware name: NXP i.MX8MPlus EVK board (DT)\n pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--)\n pc : __mutex_lock+0xd84/0x1068\n lr : __mutex_lock+0xd84/0x1068\n sp : ffffffc0864e3570\n x29: ffffffc0864e3570 x28: ffffffc0817bdc78 x27: 0000000000000003\n x26: ffffff80c54f1808 x25: ffffff80c9164080 x24: ffffffc080d723ac\n x23: 0000000000000000 x22: 0000000000000002 x21: 0000000000000000\n x20: 0000000000000000 x19: ffffffc083bc3000 x18: ffffffffffffffff\n x17: ffffffc08117b080 x16: 0000000000000002 x15: ffffff80d2d40000\n x14: 00000000000002da x13: ffffff80d2d404b8 x12: ffffffc082b5a5c8\n x11: ffffffc082bca680 x10: ffffffc082bb2640 x9 : ffffffc082bb2698\n x8 : 0000000000017fe8 x7 : c0000000ffffefff x6 : 0000000000000001\n x5 : ffffff8178fe0d48 x4 : 0000000000000000 x3 : 0000000000000027\n x2 : ffffff8178fe0d50 x1 : 0000000000000000 x0 : 0000000000000000\n Call trace:\n  __mutex_lock+0xd84/0x1068\n  mutex_lock_nested+0x28/0x34\n  tc_setup_taprio+0x118/0x68c\n  stmmac_setup_tc+0x50/0xf0\n  taprio_change+0x868/0xc9c(CVE-2024-38594)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nstm class: Fix a double free in stm_register_device()\r\n\r\nThe put_device(\u0026amp;stm-\u0026gt;dev) call will trigger stm_device_release() which\nfrees \u0026quot;stm\u0026quot; so the vfree(stm) on the next line is a double free.(CVE-2024-38627)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/shmem-helper: Fix BUG_ON() on mmap(PROT_WRITE, MAP_PRIVATE)\r\n\r\nLack of check for copy-on-write (COW) mapping in drm_gem_shmem_mmap\nallows users to call mmap with PROT_WRITE and MAP_PRIVATE flag\ncausing a kernel panic due to BUG_ON in vmf_insert_pfn_prot:\nBUG_ON((vma-\u0026gt;vm_flags \u0026amp; VM_PFNMAP) \u0026amp;\u0026amp; is_cow_mapping(vma-\u0026gt;vm_flags));\r\n\r\nReturn -EINVAL early if COW mapping is detected.\r\n\r\nThis bug affects all drm drivers using default shmem helpers.\nIt can be reproduced by this simple example:\nvoid *ptr = mmap(0, size, PROT_WRITE, MAP_PRIVATE, fd, mmap_offset);\nptr[0] = 0;(CVE-2024-39497)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nnet: hns3: fix kernel crash problem in concurrent scenario\r\n\r\nWhen link status change, the nic driver need to notify the roce\ndriver to handle this event, but at this time, the roce driver\nmay uninit, then cause kernel crash.\r\n\r\nTo fix the problem, when link status change, need to check\nwhether the roce registered, and when uninit, need to wait link\nupdate finish.(CVE-2024-39507)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nax25: Fix refcount imbalance on inbound connections\r\n\r\nWhen releasing a socket in ax25_release(), we call netdev_put() to\ndecrease the refcount on the associated ax.25 device.

Due to the different implementations depending on the\narchitecture, page_address(NULL) will trigger a panic on Loongarch\nplatform but not on x86 platform. So this bug was hidden on x86 platform\nfor a while, but now it is exposed on Loongarch platform. The root cause\nis that a zero length skb (skb-\u0026gt;len == 0) was put on the queue.\r\n\r\nThis zero length skb is a TCP FIN packet, which was sent by shutdown(),\ninvoked in test_sockmap_skb_verdict_shutdown():\r\n\r\n\tshutdown(p1, SHUT_WR);\r\n\r\nIn this case, in sk_psock_skb_ingress_enqueue(), num_sge is zero, and no\npage is put to this sge (see sg_set_page in sg_set_page), but this empty\nsge is queued into ingress_msg list.\r\n\r\nAnd in sk_msg_recvmsg(), this empty sge is used, and a NULL page is got by\nsg_page(sge).

It was found that all variables in the jffs_inode_info\nstructure were 5a5a5a5a, except for the first member sem. It is suspected that these\nvariables are not initialized because they were set to 5a5a5a5a during memory testing,\nwhich is meant to detect uninitialized memory.The sem variable is initialized in the\nfunction jffs2_i_init_once, while other members are initialized in\nthe function jffs2_init_inode_info.\r\n\r\nThe function jffs2_init_inode_info is called after iget_locked,\nbut in the iget_locked function, the destroy_inode process is triggered,\nwhich releases the inode and consequently, the target member of the inode\nis not initialized.In concurrent high pressure scenarios, iget_locked\nmay enter the destroy_inode branch as described in the code.\r\n\r\nSince the destroy_inode functionality of jffs2 only releases the target,\nthe fix method is to set target to NULL in jffs2_i_init_once.(CVE-2024-42115)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nscsi: qedf: Make qedf_execute_tmf() non-preemptible\r\n\r\nStop calling smp_processor_id() from preemptible code in\nqedf_execute_tmf90.

After\nconsidering typical scenarios, such as OpenSM processing, which can\nhandle approximately 100k packets per second, and the 1-second retry\ntimeout for most packets, we set the list size limit to 200k. Packets\nreceived beyond this limit are dropped, assuming they are likely timed\nout by the time they are handled by user-space.\r\n\r\nNotably, packets queued on the receive list due to reasons like\ntimed-out sends are preserved even when the list is full.(CVE-2024-42145)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ns390/pkey: Wipe copies of protected- and secure-keys\r\n\r\nAlthough the clear-key of neither protected- nor secure-keys is\naccessible, this key material should only be visible to the calling\nprocess.

Due to the different implementations depending on the\narchitecture, page_address(NULL) will trigger a panic on Loongarch\nplatform but not on x86 platform. So this bug was hidden on x86 platform\nfor a while, but now it is exposed on Loongarch platform. The root cause\nis that a zero length skb (skb-\u0026gt;len == 0) was put on the queue.\r\n\r\nThis zero length skb is a TCP FIN packet, which was sent by shutdown(),\ninvoked in test_sockmap_skb_verdict_shutdown():\r\n\r\n\tshutdown(p1, SHUT_WR);\r\n\r\nIn this case, in sk_psock_skb_ingress_enqueue(), num_sge is zero, and no\npage is put to this sge (see sg_set_page in sg_set_page), but this empty\nsge is queued into ingress_msg list.\r\n\r\nAnd in sk_msg_recvmsg(), this empty sge is used, and a NULL page is got by\nsg_page(sge). Pass this NULL page to copy_page_to_iter(), which passes it\nto kmap_local_page() and to page_address(), then kernel panics.\r\n\r\nTo solve this, we should skip this zero length skb. So in sk_msg_recvmsg(),\nif copy is zero, that means it\u0026apos;s a zero length skb, skip invoking\ncopy_page_to_iter().

Without this change, gve_get_ethtool_stats might make\nan invalid access on the priv-\u0026gt;stats_report-\u0026gt;stats array.(CVE-2024-42162)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nnet: dsa: mv88e6xxx: Correct check for empty list\r\n\r\nSince commit a3c53be55c95 (\u0026quot;net: dsa: mv88e6xxx: Support multiple MDIO\nbusses\u0026quot;) mv88e6xxx_default_mdio_bus() has checked that the\nreturn value of list_first_entry() is non-NULL.\r\n\r\nThis appears to be intended to guard against the list chip-\u0026gt;mdios being\nempty.  However, it is not the correct check as the implementation of\nlist_first_entry is not designed to return NULL for empty lists.\r\n\r\nInstead, use list_first_entry_or_null() which does return NULL if the\nlist is empty.\r\n\r\nFlagged by Smatch.\nCompile tested only.(CVE-2024-42224)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/amdgpu: Using uninitialized value *size when calling amdgpu_vce_cs_reloc\r\n\r\nInitialize the size before calling amdgpu_vce_cs_reloc, such as case 0x03000001.\nV2: To really improve the handling we would actually\n   need to have a separate value of 0xffffffff.(Christian)(CVE-2024-42228)",

It replaces the less informative WARN_ON_ONCE\nbacktraces with a new error handling method. This provides clearer error\nmessages and allows for the early termination of problematic sessions.\nPreviously, sessions were only released at the end of j1939_xtp_rx_rts().\n\nPotentially this could be reproduced with something like:\ntestj1939 -r vcan0:0x80 \u0026amp;\nwhile true; do\n\t# send first RTS\n\tcansend vcan0 18EC8090#1014000303002301;\n\t# send second RTS\n\tcansend vcan0 18EC8090#1014000303002301;\n\t# send abort\n\tcansend vcan0 18EC8090#ff00000000002301;\ndone(CVE-2023-52887)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: L2CAP: Fix slab-use-after-free in l2cap_connect()\n\nExtend a critical section to prevent chan from early freeing.\nAlso make the l2cap_connect() return type void. Nothing is using the\nreturned value but it is ugly to return a potentially freed pointer.\nMaking it void will help with backports because earlier kernels did use\nthe return value.

In that\nscenario, some key material from the previous key would not be\noverwritten. The easiest solution is to explicitly zeroize the entire\nprivate_key array first.\n\nNote that this patch slightly changes the behavior of this function:\npreviously, if the ecc_gen_privkey failed, the old private_key would\nremain. Now, the private_key is always zeroized.

Diag for raw\nsockets uses the pad field in struct inet_diag_req_v2 for the\nunderlying protocol. This field corresponds to the sdiag_raw_protocol\nfield in struct inet_diag_req_raw.\n\ninet_diag_get_exact_compat() converts inet_diag_req to\ninet_diag_req_v2, but leaves the pad field uninitialized.

However one of these queues\nis reserved for FCOE and thus the number of Ethernet queues should be set\nto [FP_SB_MAX_E1x -1] (15) if FCOE is enabled or [FP_SB_MAX_E1x] (16) if\nit is not.\n\nThis is also described in a comment in the source code in\ndrivers/net/ethernet/broadcom/bnx2x/bnx2x.h just above the Macro definition\nof FP_SB_MAX_E1x. Below is the part of this explanation that it important\nfor this patch\n\n/*\n  * The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is\n  * control by the number of fast-path status blocks supported by the\n  * device (HW/FW). Each fast-path status block (FP-SB) aka non-default\n  * status block represents an independent interrupts context that can\n  * serve a regular L2 networking queue. However special L2 queues such\n  * as the FCoE queue do not require a FP-SB and other components like\n  * the CNIC may consume FP-SB reducing the number of possible L2 queues\n  *\n  * If the maximum number of FP-SB available is X then:\n  * a. If CNIC is supported it consumes 1 FP-SB thus the max number of\n  *    regular L2 queues is Y=X-1\n  * b. In MF mode the actual number of L2 queues is Y= (X-1/MF_factor)\n  * c. If the FCoE L2 queue is supported the actual number of L2 queues\n  *    is Y+1\n  * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for\n  *    slow-path interrupts) or Y+2 if CNIC is supported (one additional\n  *    FP interrupt context for the CNIC).\n  * e. The number of HW context (CID count) is always X or X+1 if FCoE\n  *    L2 queue is supported. The cid for the FCoE L2 queue is always X.\n  */\n\nHowever this driver also supports NICs that use the E2 controller which can\nhandle more queues due to having more FP-SB represented by FP_SB_MAX_E2.\nLooking at the commits when the E2 support was added, it was originally\nusing the E1x parameters: commit f2e0899f0f27 (\u0026quot;bnx2x: Add 57712 support\u0026quot;).\nBack then FP_SB_MAX_E2 was set to 16 the same as E1x. However the driver\nwas later updated to take full advantage of the E2 instead of having it be\nlimited to the capabilities of the E1x. But as far as we can tell, the\narray \u0026quot;stats_query_entry query\u0026quot; was still limited to using the FP-SB\navailable to the E1x cards as part of an oversignt when the driver was\nupdated to take full advantage of the E2, and now with the driver being\naware of the greater queue size supported by E2 NICs, it causes the UBSAN\nwarnings seen in the stack traces below.\n\nThis patch increases the size of the \u0026quot;stats_query_entry query\u0026quot; array by\nreplacing FP_SB_MAX_E1x with FP_SB_MAX_E2 to be large enough to handle\nboth types of NICs.\n\nStack traces:\n\nUBSAN: array-index-out-of-bounds in\n       drivers/net/ethernet/broadcom/bnx2x/bnx2x_stats.c:1529:11\nindex 20 is out of range for type \u0026apos;stats_query_entry [19]\u0026apos;\nCPU: 12 PID: 858 Comm: systemd-network Not tainted 6.9.0-060900rc7-generic\n\t     #202405052133\nHardware name: HP ProLiant DL360 Gen9/ProLiant DL360 \n---truncated---(CVE-2024-42148)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nUSB: serial: mos7840: fix crash on resume\n\nSince commit c49cfa917025 (\u0026quot;USB: serial: use generic method if no\nalternative is provided in usb serial layer\u0026quot;), USB serial core calls the\ngeneric resume implementation when the driver has not provided one.\n\nThis can trigger a crash on resume with mos7840 since support for\nmultiple read URBs was added back in 2011.

The count of active\nbulk flows is updated whenever a flow changes state.\n\nThis has a peculiar interaction with the hash collision handling: when a\nhash collision occurs (after the set-associative hashing), the state of\nthe hash bucket is simply updated to match the new packet that collided,\nand if host fairness is enabled, that also means assigning new per-host\nstate to the flow. For this reason, the bulk flow counters of the\nhost(s) assigned to the flow are decremented, before new state is\nassigned (and the counters, which may not belong to the same host\nanymore, are incremented again).\n\nBack when this code was introduced, the host fairness mode was always\nenabled, so the decrement was unconditional. When the configuration\nflags were introduced the *increment* was made conditional, but\nthe *decrement* was not. Which of course can lead to a spurious\ndecrement (and associated wrap-around to U16_MAX).\n\nAFAICT, when host fairness is disabled, the decrement and wrap-around\nhappens as soon as a hash collision occurs (which is not that common in\nitself, due to the set-associative hashing). However, in most cases this\nis harmless, as the value is only used when host fairness mode is\nenabled. So in order to trigger an array overflow, sch_cake has to first\nbe configured with host fairness disabled, and while running in this\nmode, a hash collision has to occur to cause the overflow. Then, the\nqdisc has to be reconfigured to enable host fairness, which leads to the\narray out-of-bounds because the wrapped-around value is retained and\nused as an array index. It seems that syzbot managed to trigger this,\nwhich is quite impressive in its own right.\n\nThis patch fixes the issue by introducing the same conditional check on\ndecrement as is used on increment.\n\nThe original bug predates the upstreaming of cake, but the commit listed\nin the Fixes tag touched that code, meaning that this patch won\u0026apos;t apply\nbefore that.(CVE-2024-46828)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nperf/x86/intel: Limit the period on Haswell\n\nRunning the ltp test cve-2015-3290 concurrently reports the following\nwarnings.\n\nperfevents: irq loop stuck!\n  WARNING: CPU: 31 PID: 32438 at arch/x86/events/intel/core.c:3174\n  intel_pmu_handle_irq+0x285/0x370\n  Call Trace:\n   \u0026lt;NMI\u0026gt;\n   ? __warn+0xa4/0x220\n   ? intel_pmu_handle_irq+0x285/0x370\n   ? __report_bug+0x123/0x130\n   ? intel_pmu_handle_irq+0x285/0x370\n   ? __report_bug+0x123/0x130\n   ? intel_pmu_handle_irq+0x285/0x370\n   ? report_bug+0x3e/0xa0\n   ? handle_bug+0x3c/0x70\n   ? exc_invalid_op+0x18/0x50\n   ? asm_exc_invalid_op+0x1a/0x20\n   ? irq_work_claim+0x1e/0x40\n   ? intel_pmu_handle_irq+0x285/0x370\n   perf_event_nmi_handler+0x3d/0x60\n   nmi_handle+0x104/0x330\n\nThanks to Thomas Gleixner\u0026apos;s analysis, the issue is caused by the low\ninitial period (1) of the frequency estimation algorithm, which triggers\nthe defects of the HW, specifically erratum HSW11 and HSW143. (For the\ndetails, please refer https://lore.kernel.org/lkml/87plq9l5d2.ffs@tglx/)\n\nThe HSW11 requires a period larger than 100 for the INST_RETIRED.ALL\nevent, but the initial period in the freq mode is 1. The erratum is the\nsame as the BDM11, which has been supported in the kernel. A minimum\nperiod of 128 is enforced as well on HSW.\n\nHSW143 is regarding that the fixed counter 1 may overcount 32 with the\nHyper-Threading is enabled. However, based on the test, the hardware\nhas more issues than it tells. Besides the fixed counter 1, the message\n\u0026apos;interrupt took too long\u0026apos; can be observed on any counter which was armed\nwith a period \u0026lt; 32 and two events expired in the same NMI. A minimum\nperiod of 32 is enforced for the rest of the events.\nThe recommended workaround code of the HSW143 is not implemented.\nBecause it only addresses the issue for the fixed counter. It brings\nextra overhead through extra MSR writing. No related overcounting issue\nhas been reported so far.(CVE-2024-46848)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nocfs2: add bounds checking to ocfs2_xattr_find_entry()\n\nAdd a paranoia check to make sure it doesn\u0026apos;t stray beyond valid memory\nregion containing ocfs2 xattr entries when scanning for a match.

The intent here is\nclearly just to reset the length to zero before resubmitting, so switch to\ncalling __skb_set_length(skb, 0) directly. In addition, __skb_set_length()\nalready contains a call to skb_reset_tail_pointer(), so remove the redundant\ncall.\n\nThe syzbot report came from ath9k_hif_usb_reg_in_cb(), but there\u0026apos;s a similar\nusage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we\u0026apos;re at it.(CVE-2024-49938)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nsctp: set sk_state back to CLOSED if autobind fails in sctp_listen_start\n\nIn sctp_listen_start() invoked by sctp_inet_listen(), it should set the\nsk_state back to CLOSED if sctp_autobind() fails due to whatever reason.\n\nOtherwise, next time when calling sctp_inet_listen(), if sctp_sk(sk)-\u0026gt;reuse\nis already set via setsockopt(SCTP_REUSE_PORT), sctp_sk(sk)-\u0026gt;bind_hash will\nbe dereferenced as sk_state is LISTENING, which causes a crash as bind_hash\nis NULL.\n\n  KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]\n  RIP: 0010:sctp_inet_listen+0x7f0/0xa20 net/sctp/socket.c:8617\n  Call Trace:\n   \u0026lt;TASK\u0026gt;\n   __sys_listen_socket net/socket.c:1883 [inline]\n   __sys_listen+0x1b7/0x230 net/socket.c:1894\n   __do_sys_listen net/socket.c:1902 [inline](CVE-2024-49944)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_tables: prevent nf_skb_duplicated corruption\n\nsyzbot found that nf_dup_ipv4() or nf_dup_ipv6() could write\nper-cpu variable nf_skb_duplicated in an unsafe way [1].\n\nDisabling preemption as hinted by the splat is not enough,\nwe have to disable soft interrupts as well.\n\n[1]\nBUG: using __this_cpu_write() in preemptible [00000000] code: syz.4.282/6316\n caller is nf_dup_ipv4+0x651/0x8f0 net/ipv4/netfilter/nf_dup_ipv4.c:87\nCPU: 0 UID: 0 PID: 6316 Comm: syz.4.282 Not tainted 6.11.0-rc7-syzkaller-00104-g7052622fccb1 #0\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 08/06/2024\nCall Trace:\n \u0026lt;TASK\u0026gt;\n  __dump_stack lib/dump_stack.c:93 [inline]\n  dump_stack_lvl+0x241/0x360 lib/dump_stack.c:119\n  check_preemption_disabled+0x10e/0x120 lib/smp_processor_id.c:49\n  nf_dup_ipv4+0x651/0x8f0 net/ipv4/netfilter/nf_dup_ipv4.c:87\n  nft_dup_ipv4_eval+0x1db/0x300 net/ipv4/netfilter/nft_dup_ipv4.c:30\n  expr_call_ops_eval net/netfilter/nf_tables_core.c:240 [inline]\n  nft_do_chain+0x4ad/0x1da0 net/netfilter/nf_tables_core.c:288\n  nft_do_chain_ipv4+0x202/0x320 net/netfilter/nft_chain_filter.c:23\n  nf_hook_entry_hookfn include/linux/netfilter.h:154 [inline]\n  nf_hook_slow+0xc3/0x220 net/netfilter/core.c:626\n  nf_hook+0x2c4/0x450 include/linux/netfilter.h:269\n  NF_HOOK_COND include/linux/netfilter.h:302 [inline]\n  ip_output+0x185/0x230 net/ipv4/ip_output.c:433\n  ip_local_out net/ipv4/ip_output.c:129 [inline]\n  ip_send_skb+0x74/0x100 net/ipv4/ip_output.c:1495\n  udp_send_skb+0xacf/0x1650 net/ipv4/udp.c:981\n  udp_sendmsg+0x1c21/0x2a60 net/ipv4/udp.c:1269\n  sock_sendmsg_nosec net/socket.c:730 [inline]\n  __sock_sendmsg+0x1a6/0x270 net/socket.c:745\n  ____sys_sendmsg+0x525/0x7d0 net/socket.c:2597\n  ___sys_sendmsg net/socket.c:2651 [inline]\n  __sys_sendmmsg+0x3b2/0x740 net/socket.c:2737\n  __do_sys_sendmmsg net/socket.c:2766 [inline]\n  __se_sys_sendmmsg net/socket.c:2763 [inline]\n  __x64_sys_sendmmsg+0xa0/0xb0 net/socket.c:2763\n  do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n  do_syscall_64+0xf3/0x230 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x77/0x7f\nRIP: 0033:0x7f4ce4f7def9\nCode: ff ff c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 \u0026lt;48\u0026gt; 3d 01 f0 ff ff 73 01 c3 48 c7 c1 a8 ff ff ff f7 d8 64 89 01 48\nRSP: 002b:00007f4ce5d4a038 EFLAGS: 00000246 ORIG_RAX: 0000000000000133\nRAX: ffffffffffffffda RBX: 00007f4ce5135f80 RCX: 00007f4ce4f7def9\nRDX: 0000000000000001 RSI: 0000000020005d40 RDI: 0000000000000006\nRBP: 00007f4ce4ff0b76 R08: 0000000000000000 R09: 0000000000000000\nR10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000\nR13: 0000000000000000 R14: 00007f4ce5135f80 R15: 00007ffd4cbc6d68\n \u0026lt;/TASK\u0026gt;(CVE-2024-49952)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\njbd2: stop waiting for space when jbd2_cleanup_journal_tail() returns error\n\nIn __jbd2_log_wait_for_space(), we might call jbd2_cleanup_journal_tail()\nto recover some journal space.

We measured the time of\nthe loop inside read_efuse_byte() alone, and in this reproducer (which\ninvolves the dummy_hcd emulation layer), it takes 15 seconds each.

The pci_bus is destroyed\nbefore the pci_slot, so a use-after-free ensues when pci_slot_release()\naccesses slot-\u0026gt;bus.\n\nIn principle this should not happen because pci_stop_bus_device() unbinds\npciehp (and therefore destroys the pci_slot) before the pci_bus is\ndestroyed by pci_remove_bus_device().\n\nHowever the stacktrace provided by Dennis shows that pciehp is unbound from\npci_remove_bus_device() instead of pci_stop_bus_device().  To understand\nthe significance of this, one needs to know that the PCI core uses a two\nstep process to remove a portion of the hierarchy:  It first unbinds all\ndrivers in the sub-hierarchy in pci_stop_bus_device() and then actually\nremoves the devices in pci_remove_bus_device().  There is no precaution to\nprevent driver binding in-between pci_stop_bus_device() and\npci_remove_bus_device().\n\nIn Dennis\u0026apos; case, it seems removal of the hierarchy by pciehp races with\ndriver binding by pci_bus_add_devices().  pciehp is bound to the\nDownstream Port after pci_stop_bus_device() has run, so it is unbound by\npci_remove_bus_device() instead of pci_stop_bus_device().  Because the\npci_bus has already been destroyed at that point, accesses to it result in\na use-after-free.\n\nOne might conclude that driver binding needs to be prevented after\npci_stop_bus_device() has run.  However it seems risky that pci_slot points\nto pci_bus without holding a reference.  Solely relying on correct ordering\nof driver unbind versus pci_bus destruction is certainly not defensive\nprogramming.\n\nIf pci_slot has a need to access data in pci_bus, it ought to acquire a\nreference.  Amend pci_create_slot() accordingly.  Dennis reports that the\ncrash is not reproducible with this change.\n\nAbridged stacktrace:\n\n  pcieport 0000:00:07.0: PME: Signaling with IRQ 156\n  pcieport 0000:00:07.0: pciehp: Slot #12 AttnBtn- PwrCtrl- MRL- AttnInd- PwrInd- HotPlug+ Surprise+ Interlock- NoCompl+ IbPresDis- LLActRep+\n  pci_bus 0000:20: dev 00, created physical slot 12\n  pcieport 0000:00:07.0: pciehp: Slot(12): Card not present\n  ...\n  pcieport 0000:21:02.0: pciehp: pcie_disable_notification: SLOTCTRL d8 write cmd 0\n  Oops: general protection fault, probably for non-canonical address 0x6b6b6b6b6b6b6b6b: 0000 [#1] PREEMPT SMP NOPTI\n  CPU: 13 UID: 0 PID: 134 Comm: irq/156-pciehp Not tainted 6.11.0-devel+ #1\n  RIP: 0010:dev_driver_string+0x12/0x40\n  pci_destroy_slot\n  pciehp_remove\n  pcie_port_remove_service\n  device_release_driver_internal\n  bus_remove_device\n  device_del\n  device_unregister\n  remove_iter\n  device_for_each_child\n  pcie_portdrv_remove\n  pci_device_remove\n  device_release_driver_internal\n  bus_remove_device\n  device_del\n  pci_remove_bus_device (recursive invocation)\n  pci_remove_bus_device\n  pciehp_unconfigure_device\n  pciehp_disable_slot\n  pciehp_handle_presence_or_link_change\n  pciehp_ist(CVE-2024-53194)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nKVM: arm64: Don\u0026apos;t retire aborted MMIO instruction\n\nReturning an abort to the guest for an unsupported MMIO access is a\ndocumented feature of the KVM UAPI.

Note that while userspace\nis capable of pending an asynchronous exception (SError, IRQ, or FIQ),\nit is still safe to retire the MMIO instruction in this case as (1) they\nare by definition asynchronous, and (2) KVM relies on hardware support\nfor pending/delivering these exceptions instead of the software state\nmachine for advancing PC.(CVE-2024-53196)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nusb: typec: fix potential array underflow in ucsi_ccg_sync_control()\n\nThe \u0026quot;command\u0026quot; variable can be controlled by the user via debugfs.

As for now, the maximal read size for kvec iter is\nonly limited by fc-\u0026gt;max_read. For virtio-fs, max_read is UINT_MAX, so\nfuse_direct_io() doesn\u0026apos;t split the 10MB buffer. It saves the address and\nthe size of the 10MB-sized buffer in out_args[0] of a fuse request and\npasses the fuse request to virtio_fs_wake_pending_and_unlock().\n\n4) virtio_fs_wake_pending_and_unlock() uses virtio_fs_enqueue_req() to\nqueue the request. Because virtiofs need DMA-able address, so\nvirtio_fs_enqueue_req() uses kmalloc() to allocate a bounce buffer for\nall fuse args, copies these args into the bounce buffer and passed the\nphysical address of the bounce buffer to virtiofsd. The total length of\nthese fuse args for the passed fuse request is about 10MB, so\ncopy_args_to_argbuf() invokes kmalloc() with a 10MB size parameter and\nit triggers the warning in __alloc_pages():\n\n\tif (WARN_ON_ONCE_GFP(order \u0026gt; MAX_PAGE_ORDER, gfp))\n\t\treturn NULL;\n\n5) virtio_fs_enqueue_req() will retry the memory allocation in a\nkworker, but it won\u0026apos;t help, because kmalloc() will always return NULL\ndue to the abnormal size and finit_module() will hang forever.\n\nA feasible solution is to limit the value of max_read for virtio-fs, so\nthe length passed to kmalloc() will be limited. However it will affect\nthe maximal read size for normal read. And for virtio-fs write initiated\nfrom kernel, it has the similar problem but now there is no way to limit\nfc-\u0026gt;max_write in kernel.\n\nSo instead of limiting both the values of max_read and max_write in\nkernel, introducing use_pages_for_kvec_io in fuse_conn and setting it as\ntrue in virtiofs. When use_pages_for_kvec_io is enabled, fuse will use\npages instead of pointer to pass the KVEC_IO data.\n\nAfter switching to pages for KVEC_IO data, these pages will be used for\nDMA through virtio-fs. If these pages are backed by vmalloc(),\n{flush|invalidate}_kernel_vmap_range() are necessary to flush or\ninvalidate the cache before the DMA operation.

However, bpf_map_alloc_id() invokes\nidr_alloc_cyclic() after acquiring map_idr_lock, it will trigger a\nsimilar lockdep warning because the slab\u0026apos;s lock (s-\u0026gt;cpu_slab-\u0026gt;lock) is\nstill a spinlock.\n\nInstead of changing map_idr_lock\u0026apos;s type, fix the issue by invoking\nhtab_put_fd_value() after htab_unlock_bucket(). However, only deferring\nthe invocation of htab_put_fd_value() is not enough, because the old map\npointers in htab of maps can not be saved during batched deletion.\nTherefore, also defer the invocation of free_htab_elem(), so these\nto-be-freed elements could be linked together similar to lru map.\n\nThere are four callers for -\u0026gt;map_fd_put_ptr:\n\n(1) alloc_htab_elem() (through htab_put_fd_value())\nIt invokes -\u0026gt;map_fd_put_ptr() under a raw_spinlock_t. The invocation of\nhtab_put_fd_value() can not simply move after htab_unlock_bucket(),\nbecause the old element has already been stashed in htab-\u0026gt;extra_elems.\nIt may be reused immediately after htab_unlock_bucket() and the\ninvocation of htab_put_fd_value() after htab_unlock_bucket() may release\nthe newly-added element incorrectly. Therefore, saving the map pointer\nof the old element for htab of maps before unlocking the bucket and\nreleasing the map_ptr after unlock.

The return value of nilfs_last_byte()\nis also of type \u0026quot;unsigned int\u0026quot;, but it is truncated so as not to exceed\nPAGE_SIZE and no bit loss occurs, so no change is required.(CVE-2024-56619)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nscsi: ufs: core: sysfs: Prevent div by zero\n\nPrevent a division by 0 when monitoring is not enabled.(CVE-2024-56622)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: fix Out-of-Bounds Write in ksmbd_vfs_stream_write\n\nAn offset from client could be a negative value, It could allows\nto write data outside the bounds of the allocated buffer.\nNote that this issue is coming when setting\n\u0026apos;vfs objects = streams_xattr parameter\u0026apos; in ksmbd.conf..(CVE-2024-56626)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nscsi: sg: Fix slab-use-after-free read in sg_release()\n\nFix a use-after-free bug in sg_release(), detected by syzbot with KASAN:\n\nBUG: KASAN: slab-use-after-free in lock_release+0x151/0xa30\nkernel/locking/lockdep.c:5838\n__mutex_unlock_slowpath+0xe2/0x750 kernel/locking/mutex.c:912\nsg_release+0x1f4/0x2e0 drivers/scsi/sg.c:407\n\nIn sg_release(), the function kref_put(\u0026amp;sfp-\u0026gt;f_ref, sg_remove_sfp) is\ncalled before releasing the open_rel_lock mutex. The kref_put() call may\ndecrement the reference count of sfp to zero, triggering its cleanup\nthrough sg_remove_sfp(). This cleanup includes scheduling deferred work\nvia sg_remove_sfp_usercontext(), which ultimately frees sfp.\n\nAfter kref_put(), sg_release() continues to unlock open_rel_lock and may\nreference sfp or sdp. If sfp has already been freed, this results in a\nslab-use-after-free error.\n\nMove the kref_put(\u0026amp;sfp-\u0026gt;f_ref, sg_remove_sfp) call after unlocking the\nopen_rel_lock mutex. This ensures:\n\n - No references to sfp or sdp occur after the reference count is\n   decremented.\n\n - Cleanup functions such as sg_remove_sfp() and\n   sg_remove_sfp_usercontext() can safely execute without impacting the\n   mutex handling in sg_release().\n\nThe fix has been tested and validated by syzbot.

If a barrier is missing, it may cause cookie2 to remain in the\n-wait- process indefinitely.\n\nIn commit 3288666c7256 (\u0026quot;fscache: Use clear_and_wake_up_bit() in\nfscache_create_volume_work()\u0026quot;), barriers were added to similar operations\nin fscache_create_volume_work(), but fscache_create_volume() was missed.\n\nBy combining the clear and wake operations into clear_and_wake_up_bit() to\nfix this issue.(CVE-2024-56755)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nnvme-pci: fix freeing of the HMB descriptor table\n\nThe HMB descriptor table is sized to the maximum number of descriptors\nthat could be used for a given device, but __nvme_alloc_host_mem could\nbreak out of the loop earlier on memory allocation failure and end up\nusing less descriptors than planned for, which leads to an incorrect\nsize passed to dma_free_coherent.\n\nIn practice this was not showing up because the number of descriptors\ntends to be low and the dma coherent allocator always allocates and\nfrees at least a page.(CVE-2024-56756)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: fix use-after-free when COWing tree bock and tracing is enabled\n\nWhen a COWing a tree block, at btrfs_cow_block(), and we have the\ntracepoint trace_btrfs_cow_block() enabled and preemption is also enabled\n(CONFIG_PREEMPT=y), we can trigger a use-after-free in the COWed extent\nbuffer while inside the tracepoint code. This is because in some paths\nthat call btrfs_cow_block(), such as btrfs_search_slot(), we are holding\nthe last reference on the extent buffer @buf so btrfs_force_cow_block()\ndrops the last reference on the @buf extent buffer when it calls\nfree_extent_buffer_stale(buf), which schedules the release of the extent\nbuffer with RCU. This means that if we are on a kernel with preemption,\nthe current task may be preempted before calling trace_btrfs_cow_block()\nand the extent buffer already released by the time trace_btrfs_cow_block()\nis called, resulting in a use-after-free.\n\nFix this by moving the trace_btrfs_cow_block() from btrfs_cow_block() to\nbtrfs_force_cow_block() before the COWed extent buffer is freed.\nThis also has a side effect of invoking the tracepoint in the tree defrag\ncode, at defrag.c:btrfs_realloc_node(), since btrfs_force_cow_block() is\ncalled there, but this is fine and it was actually missing there.(CVE-2024-56759)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\ntracing: Prevent bad count for tracing_cpumask_write\n\nIf a large count is provided, it will trigger a warning in bitmap_parse_user.\nAlso check zero for it.(CVE-2024-56763)",
