"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: tls: handle backlogging of crypto requests\n\nSince we\u0027re setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on our\nrequests to the crypto API, crypto_aead_{encrypt,decrypt} can return\n -EBUSY instead of -EINPROGRESS in valid situations. For example, when\nthe cryptd queue for AESNI is full (easy to trigger with an\nartificially low cryptd.cryptd_max_cpu_qlen), requests will be enqueued\nto the backlog but still processed. In that case, the async callback\nwill also be called twice: first with err == -EINPROGRESS, which it\nseems we can just ignore, then with err == 0.\n\nCompared to Sabrina\u0027s original patch this version uses the new\ntls_*crypt_async_wait() helpers and converts the EBUSY to\nEINPROGRESS to avoid having to modify all the error handling\npaths. The handling is identical.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nsched/rt: Fix race in push_rt_task\n\nOverview\n========\nWhen a CPU chooses to call push_rt_task and picks a task to push to\nanother CPU\u0027s runqueue then it will call find_lock_lowest_rq method\nwhich would take a double lock on both CPUs\u0027 runqueues. If one of the\nlocks aren\u0027t readily available, it may lead to dropping the current\nrunqueue lock and reacquiring both the locks at once. During this window\nit is possible that the task is already migrated and is running on some\nother CPU. These cases are already handled. However, if the task is\nmigrated and has already been executed and another CPU is now trying to\nwake it up (ttwu) such that it is queued again on the runqeue\n(on_rq is 1) and also if the task was run by the same CPU, then the\ncurrent checks will pass even though the task was migrated out and is no\nlonger in the pushable tasks list.\n\nCrashes\n=======\nThis bug resulted in quite a few flavors of crashes triggering kernel\npanics with various crash signatures such as assert failures, page\nfaults, null pointer dereferences, and queue corruption errors all\ncoming from scheduler itself.\n\nSome of the crashes:\n-\u003e kernel BUG at kernel/sched/rt.c:1616!

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: qgroup: fix race between quota disable and quota rescan ioctl\n\nThere\u0027s a race between a task disabling quotas and another running the\nrescan ioctl that can result in a use-after-free of qgroup records from\nthe fs_info-\u003eqgroup_tree rbtree.\n\nThis happens as follows:\n\n1) Task A enters btrfs_ioctl_quota_rescan() -\u003e btrfs_qgroup_rescan();\n\n2) Task B enters btrfs_quota_disable() and calls\n btrfs_qgroup_wait_for_completion(), which does nothing because at that\n point fs_info-\u003eqgroup_rescan_running is false (it wasn\u0027t set yet by\n task A);\n\n3) Task B calls btrfs_free_qgroup_config() which starts freeing qgroups\n from fs_info-\u003eqgroup_tree without taking the lock fs_info-\u003eqgroup_lock;\n\n4) Task A enters qgroup_rescan_zero_tracking() which starts iterating\n the fs_info-\u003eqgroup_tree tree while holding fs_info-\u003eqgroup_lock,\n but task B is freeing qgroup records from that tree without holding\n the lock, resulting in a use-after-free.\n\nFix this by taking fs_info-\u003eqgroup_lock at btrfs_free_qgroup_config().\nAlso at btrfs_qgroup_rescan() don\u0027t start the rescan worker if quotas\nwere already disabled.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: do not free data reservation in fallback from inline due to -ENOSPC\n\nIf we fail to create an inline extent due to -ENOSPC, we will attempt to\ngo through the normal COW path, reserve an extent, create an ordered\nextent, etc. However we were always freeing the reserved qgroup data,\nwhich is wrong since we will use data. Fix this by freeing the reserved\nqgroup data in __cow_file_range_inline() only if we are not doing the\nfallback (ret is \u003c= 0).",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nipvlan: Make the addrs_lock be per port\n\nMake the addrs_lock be per port, not per ipvlan dev.\n\nInitial code seems to be written in the assumption,\nthat any address change must occur under RTNL.\nBut it is not so for the case of IPv6. So\n\n1) Introduce per-port addrs_lock.\n\n2) It was needed to fix places where it was forgotten\nto take lock (ipvlan_open/ipvlan_close)\n\nThis appears to be a very minor problem though.\nSince it\u0027s highly unlikely that ipvlan_add_addr() will\nbe called on 2 CPU simultaneously. But nevertheless,\nthis could cause:\n\n1) False-negative of ipvlan_addr_busy(): one interface\niterated through all port-\u003eipvlans + ipvlan-\u003eaddrs\nunder some ipvlan spinlock, and another added IP\nunder its own lock. Though this is only possible\nfor IPv6, since looks like only ipvlan_addr6_event() can be\ncalled without rtnl_lock.\n\n2) Race since ipvlan_ht_addr_add(port) is called under\ndifferent ipvlan-\u003eaddrs_lock locks\n\nThis should not affect performance, since add/remove IP\nis a rare situation and spinlock is not taken on fast\npaths.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\ngve: Fix stats report corruption on queue count change\n\nThe driver and the NIC share a region in memory for stats reporting.\nThe NIC calculates its offset into this region based on the total size\nof the stats region and the size of the NIC\u0027s stats.\n\nWhen the number of queues is changed, the driver\u0027s stats region is\nresized. If the queue count is increased, the NIC can write past\nthe end of the allocated stats region, causing memory corruption.\nIf the queue count is decreased, there is a gap between the driver\nand NIC stats, leading to incorrect stats reporting.\n\nThis change fixes the issue by allocating stats region with maximum\nsize, and the offset calculation for NIC stats is changed to match\nwith the calculation of the NIC.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_tables: unconditionally bump set-\u003enelems before insertion\n\nIn case that the set is full, a new element gets published then removed\nwithout waiting for the RCU grace period, while RCU reader can be\nwalking over it already.\n\nTo address this issue, add the element transaction even if set is full,\nbut toggle the set_full flag to report -ENFILE so the abort path safely\nunwinds the set to its previous state.\n\nAs for element updates, decrement set-\u003enelems to restore it.\n\nA simpler fix is to call synchronize_rcu() in the error path.\nHowever, with a large batch adding elements to already maxed-out set,\nthis could cause noticeable slowdown of such batches.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: teql: fix NULL pointer dereference in iptunnel_xmit on TEQL slave xmit\n\nteql_master_xmit() calls netdev_start_xmit(skb, slave) to transmit\nthrough slave devices, but does not update skb-\u003edev to the slave device\nbeforehand.\n\nWhen a gretap tunnel is a TEQL slave, the transmit path reaches\niptunnel_xmit() which saves dev = skb-\u003edev (still pointing to teql0\nmaster) and later calls iptunnel_xmit_stats(dev, pkt_len). This\nfunction does:\n\n get_cpu_ptr(dev-\u003etstats)\n\nSince teql_master_setup() does not set dev-\u003epcpu_stat_type to\nNETDEV_PCPU_STAT_TSTATS, the core network stack never allocates tstats\nfor teql0, so dev-\u003etstats is NULL. get_cpu_ptr(NULL) computes\nNULL + __per_cpu_offset[cpu], resulting in a page fault.\n\n BUG: unable to handle page fault for address: ffff8880e6659018\n #PF: supervisor write access in kernel mode\n #PF: error_code(0x0002) - not-present page\n PGD 68bc067 P4D 68bc067 PUD 0\n Oops: Oops: 0002 [#1] SMP KASAN PTI\n RIP: 0010:iptunnel_xmit (./include/net/ip_tunnels.h:664 net/ipv4/ip_tunnel_core.c:89)\n Call Trace:\n \u003cTASK\u003e\n ip_tunnel_xmit (net/ipv4/ip_tunnel.c:847)\n __gre_xmit (net/ipv4/ip_gre.c:478)\n gre_tap_xmit (net/ipv4/ip_gre.c:779)\n teql_master_xmit (net/sched/sch_teql.c:319)\n dev_hard_start_xmit (net/core/dev.c:3887)\n sch_direct_xmit (net/sched/sch_generic.c:347)\n __dev_queue_xmit (net/core/dev.c:4802)\n neigh_direct_output (net/core/neighbour.c:1660)\n ip_finish_output2 (net/ipv4/ip_output.c:237)\n __ip_finish_output.part.0 (net/ipv4/ip_output.c:315)\n ip_mc_output (net/ipv4/ip_output.c:369)\n ip_send_skb (net/ipv4/ip_output.c:1508)\n udp_send_skb (net/ipv4/udp.c:1195)\n udp_sendmsg (net/ipv4/udp.c:1485)\n inet_sendmsg (net/ipv4/af_inet.c:859)\n __sys_sendto (net/socket.c:2206)\n\nFix this by setting skb-\u003edev = slave before calling\nnetdev_start_xmit(), so that tunnel xmit functions see the correct\nslave device with properly allocated tstats.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usb-audio: Use correct version for UAC3 header validation\n\nThe entry of the validators table for UAC3 AC header descriptor is\ndefined with the wrong protocol version UAC_VERSION_2, while it should\nhave been UAC_VERSION_3. This results in the validator never matching\nfor actual UAC3 devices (protocol == UAC_VERSION_3), causing their\nheader descriptors to bypass validation entirely. A malicious USB\ndevice presenting a truncated UAC3 header could exploit this to cause\nout-of-bounds reads when the driver later accesses unvalidated\ndescriptor fields.\n\nThe bug was introduced in the same commit as the recently fixed UAC3\nfeature unit sub-type typo, and appears to be from the same copy-paste\nerror when the UAC3 section was created from the UAC2 section.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\ncan: bcm: fix locking for bcm_op runtime updates\n\nCommit c2aba69d0c36 (\"can: bcm: add locking for bcm_op runtime updates\")\nadded a locking for some variables that can be modified at runtime when\nupdating the sending bcm_op with a new TX_SETUP command in bcm_tx_setup().\n\nUsually the RX_SETUP only handles and filters incoming traffic with one\nexception: When the RX_RTR_FRAME flag is set a predefined CAN frame is\nsent when a specific RTR frame is received. Therefore the rx bcm_op uses\nbcm_can_tx() which uses the bcm_tx_lock that was only initialized in\nbcm_tx_setup(). Add the missing spin_lock_init() when allocating the\nbcm_op in bcm_rx_setup() to handle the RTR case properly.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\ngve: fix incorrect buffer cleanup in gve_tx_clean_pending_packets for QPL\n\nIn DQ-QPL mode, gve_tx_clean_pending_packets() incorrectly uses the RDA\nbuffer cleanup path. It iterates num_bufs times and attempts to unmap\nentries in the dma array.\n\nThis leads to two issues:\n1. The dma array shares storage with tx_qpl_buf_ids (union).\n Interpreting buffer IDs as DMA addresses results in attempting to\n unmap incorrect memory locations.\n2. num_bufs in QPL mode (counting 2K chunks) can significantly exceed\n the size of the dma array, causing out-of-bounds access warnings\n(trace below is how we noticed this issue).\n\nUBSAN: array-index-out-of-bounds in\ndrivers/net/ethernet/drivers/net/ethernet/google/gve/gve_tx_dqo.c:178:5 index 18 is out of\nrange for type \u0027dma_addr_t[18]\u0027 (aka \u0027unsigned long long[18]\u0027)\nWorkqueue: gve gve_service_task [gve]\nCall Trace:\n\u003cTASK\u003e\ndump_stack_lvl+0x33/0xa0\n__ubsan_handle_out_of_bounds+0xdc/0x110\ngve_tx_stop_ring_dqo+0x182/0x200 [gve]\ngve_close+0x1be/0x450 [gve]\ngve_reset+0x99/0x120 [gve]\ngve_service_task+0x61/0x100 [gve]\nprocess_scheduled_works+0x1e9/0x380\n\nFix this by properly checking for QPL mode and delegating to\ngve_free_tx_qpl_bufs() to reclaim the buffers.",
