Title

drm/amd/display: Implement bounds check for stream encoder creation in DCN301

Summary

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Implement bounds check for stream encoder creation in DCN301 'stream_enc_regs' array is an array of dcn10_stream_enc_registers structures. The array is initialized with four elements, corresponding to the four calls to stream_enc_regs() in the array initializer. This means that valid indices for this array are 0, 1, 2, and 3. The error message 'stream_enc_regs' 4 <= 5 below, is indicating that there is an attempt to access this array with an index of 5, which is out of bounds. This could lead to undefined behavior Here, eng_id is used as an index to access the stream_enc_regs array. If eng_id is 5, this would result in an out-of-bounds access on the stream_enc_regs array. Thus fixing Buffer overflow error in dcn301_stream_encoder_create reported by Smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn301/dcn301_resource.c:1011 dcn301_stream_encoder_create() error: buffer overflow 'stream_enc_regs' 4 <= 5

Title

tipc: Check the bearer type before calling tipc_udp_nl_bearer_add()

Summary

In the Linux kernel, the following vulnerability has been resolved: tipc: Check the bearer type before calling tipc_udp_nl_bearer_add() syzbot reported the following general protection fault [1]: general protection fault, probably for non-canonical address 0xdffffc0000000010: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range [0x0000000000000080-0x0000000000000087] ... RIP: 0010:tipc_udp_is_known_peer+0x9c/0x250 net/tipc/udp_media.c:291 ...

This patch fixes the issue by checking the bearer type before calling tipc_udp_nl_bearer_add() in tipc_nl_bearer_add().

The corrupted `pd-\u003ecpumask` also redirects `rdmsr_on_cpu()` targets for the sysfs temperature readers.\nI:H - This is an out-of-bounds write that clobbers a live kernel pointer, the xarray spinlock and flags, and the CPU mask inside `struct platform_data`. The resulting type confusion lets `__set_bit()` in `ida_alloc_range()` write into misinterpreted kernel memory, and corrupted `core_data[]`/cpumask state can drive bogus `kfree()` and stale-sysfs teardown in `coretemp_remove_core()`.\nA:H - Once `xa_head` is corrupted, the next IDA operation walks a garbage or non-canonical pointer, producing an immediate oops or GP fault; corrupting the xarray spinlock can also wedge the hotplug path.

The L3 source address is unconstrained (only unspecified/multicast/loopback sources are filtered), so an off-link remote sender whose packet is routed to a workload behind the overlay reaches the vulnerable code.\nAC:L - The attacker only needs to send an IPv6 packet larger than the tunnel\u0027s inner MTU; non-linear skbs are the normal case for large frames under GRO, header-split NICs, and virtio-net mergeable buffers, and the reporter reproduced it with plain netperf traffic. No memory-layout luck or attacker-uncontrollable state is required.\nPR:N - There is no capability check, authentication, or credential gate anywhere on the receive-and-bridge-to-tunnel path \u2014 the packet is simply forwarded and the ICMPv6 error is built. The attacker needs no account or privileges on the affected host.\nUI:N - Exploitation is entirely packet-driven and happens inside softirq/xmit context with no victim participation. No administrator or user action is needed once the standard bridged-tunnel configuration is in place.\nS:U - The out-of-bounds read and its consequences are confined to the host kernel that contains the defective checksum call. The vulnerable and impacted components are the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - csum_partial() reads a fixed 1240 bytes from a linear buffer that may hold only tens of bytes, overreading up to roughly a kilobyte of adjacent kernel slab memory \u2014 far beyond a \"few bytes.\" Worse, the folded result is placed in the ICMPv6 checksum field and transmitted back to the attacker, yielding a repeatable oracle over kernel heap contents that heap grooming can turn into a real disclosure.\nI:N - The defect is a read-only overrun; no kernel memory is written, no bounds are exceeded on a store, and there is no type confusion or control-flow influence. The only consequence for state is an incorrect checksum on an outgoing packet, which the receiver discards.\nA:H - Reading up to ~1KB past the end of a slab allocation can walk off the backing pages into unmapped memory, faulting in softirq context and oopsing the kernel. On KASAN or panic_on_oops/hardened kernels the access panics the machine outright, and the attacker can repeat it at will with a stream of oversized packets."

CVE-2024-26667 (GCVE-0-2024-26667)

Vulnerability from cvelistv5 – Published: 2024-04-02 06:22 – Updated: 2026-05-11 20:01

Title

drm/msm/dpu: check for valid hw_pp in dpu_encoder_helper_phys_cleanup

Summary

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: check for valid hw_pp in dpu_encoder_helper_phys_cleanup The commit 8b45a26f2ba9 ("drm/msm/dpu: reserve cdm blocks for writeback in case of YUV output") introduced a smatch warning about another conditional block in dpu_encoder_helper_phys_cleanup() which had assumed hw_pp will always be valid which may not necessarily be true. Lets fix the other conditional block by making sure hw_pp is valid before dereferencing it. Patchwork: https://patchwork.freedesktop.org/patch/574878/

CVE-2024-26671 (GCVE-0-2024-26671)

Vulnerability from cvelistv5 – Published: 2024-04-02 06:49 – Updated: 2026-10-15 00:38

Title

blk-mq: fix IO hang from sbitmap wakeup race

Summary

In the Linux kernel, the following vulnerability has been resolved: blk-mq: fix IO hang from sbitmap wakeup race In blk_mq_mark_tag_wait(), __add_wait_queue() may be re-ordered with the following blk_mq_get_driver_tag() in case of getting driver tag failure. Then in __sbitmap_queue_wake_up(), waitqueue_active() may not observe the added waiter in blk_mq_mark_tag_wait() and wake up nothing, meantime blk_mq_mark_tag_wait() can't get driver tag successfully. This issue can be reproduced by running the following test in loop, and fio hang can be observed in < 30min when running it on my test VM in laptop. modprobe -r scsi_debug modprobe scsi_debug delay=0 dev_size_mb=4096 max_queue=1 host_max_queue=1 submit_queues=4 dev=`ls -d /sys/bus/pseudo/drivers/scsi_debug/adapter*/host*/target*/*/block/* | head -1 | xargs basename` fio --filename=/dev/"$dev" --direct=1 --rw=randrw --bs=4k --iodepth=1 \ --runtime=100 --numjobs=40 --time_based --name=test \ --ioengine=libaio Fix the issue by adding one explicit barrier in blk_mq_mark_tag_wait(), which is just fine in case of running out of tag.

CVE-2024-26676 (GCVE-0-2024-26676)

Title

af_unix: Call kfree_skb() for dead unix_(sk)->oob_skb in GC.

Summary

In the Linux kernel, the following vulnerability has been resolved: af_unix: Call kfree_skb() for dead unix_(sk)->oob_skb in GC. syzbot reported a warning [0] in __unix_gc() with a repro, which creates a socketpair and sends one socket's fd to itself using the peer. socketpair(AF_UNIX, SOCK_STREAM, 0, [3, 4]) = 0 sendmsg(4, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\360", iov_len=1}], msg_iovlen=1, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[3]}], msg_controllen=24, msg_flags=0}, MSG_OOB|MSG_PROBE|MSG_DONTWAIT|MSG_ZEROCOPY) = 1 This forms a self-cyclic reference that GC should finally untangle but does not due to lack of MSG_OOB handling, resulting in memory leak. Recently, commit 11498715f266 ("af_unix: Remove io_uring code for GC.") removed io_uring's dead code in GC and revealed the problem. The code was executed at the final stage of GC and unconditionally moved all GC candidates from gc_candidates to gc_inflight_list. That papered over the reported problem by always making the following WARN_ON_ONCE(!list_empty(&gc_candidates)) false. The problem has been there since commit 2aab4b969002 ("af_unix: fix struct pid leaks in OOB support") added full scm support for MSG_OOB while fixing another bug. To fix this problem, we must call kfree_skb() for unix_sk(sk)->oob_skb if the socket still exists in gc_candidates after purging collected skb. Then, we need to set NULL to oob_skb before calling kfree_skb() because it calls last fput() and triggers unix_release_sock(), where we call duplicate kfree_skb(u->oob_skb) if not NULL. Note that the leaked socket remained being linked to a global list, so kmemleak also could not detect it. We need to check /proc/net/protocol to notice the unfreed socket.

We need to check /proc/net/protocol\nto notice the unfreed socket.\n\n[0]:\nWARNING: CPU: 0 PID: 2863 at net/unix/garbage.c:345 __unix_gc+0xc74/0xe80 net/unix/garbage.c:345\nModules linked in:\nCPU: 0 PID: 2863 Comm: kworker/u4:11 Not tainted 6.8.0-rc1-syzkaller-00583-g1701940b1a02 #0\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/25/2024\nWorkqueue: events_unbound __unix_gc\nRIP: 0010:__unix_gc+0xc74/0xe80 net/unix/garbage.c:345\nCode: 8b 5c 24 50 e9 86 f8 ff ff e8 f8 e4 22 f8 31 d2 48 c7 c6 30 6a 69 89 4c 89 ef e8 97 ef ff ff e9 80 f9 ff ff e8 dd e4 22 f8 90 \u003c0f\u003e 0b 90 e9 7b fd ff ff 48 89 df e8 5c e7 7c f8 e9 d3 f8 ff ff e8\nRSP: 0018:ffffc9000b03fba0 EFLAGS: 00010293\nRAX: 0000000000000000 RBX: ffffc9000b03fc10 RCX: ffffffff816c493e\nRDX: ffff88802c02d940 RSI: ffffffff896982f3 RDI: ffffc9000b03fb30\nRBP: ffffc9000b03fce0 R08: 0000000000000001 R09: fffff52001607f66\nR10: 0000000000000003 R11: 0000000000000002 R12: dffffc0000000000\nR13: ffffc9000b03fc10 R14: ffffc9000b03fc10 R15: 0000000000000001\nFS:  0000000000000000(0000) GS:ffff8880b9400000(0000) knlGS:0000000000000000\nCS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 00005559c8677a60 CR3: 000000000d57a000 CR4: 00000000003506f0\nDR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\nDR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\nCall Trace:\n \u003cTASK\u003e\n process_one_work+0x889/0x15e0 kernel/workqueue.c:2633\n process_scheduled_works kernel/workqueue.c:2706 [inline]\n worker_thread+0x8b9/0x12a0 kernel/workqueue.c:2787\n kthread+0x2c6/0x3b0 kernel/kthread.c:388\n ret_from_fork+0x45/0x80 arch/x86/kernel/process.c:147\n ret_from_fork_asm+0x1b/0x30 arch/x86/entry/entry_64.S:242\n \u003c/TASK\u003e"
