| CVE-2024-50001 | 1 Linux | 1 Linux Kernel | 2026-08-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix error path in multi-packet WQE transmit Remove the erroneous unmap in case no DMA mapping was established The multi-packet WQE transmit code attempts to obtain a DMA mapping for the skb. This could fail, e.g. under memory pressure, when the IOMMU driver just can't allocate more memory for page tables. While the code tries to handle this in the path below the err_unmap label it erroneously unmaps one entry from the sq's FIFO list of active mappings. Since the current map attempt failed this unmap is removing some random DMA mapping that might still be required. If the PCI function now presents that IOVA, the IOMMU may assumes a rogue DMA access and e.g. on s390 puts the PCI function in error state. The erroneous behavior was seen in a stress-test environment that created memory pressure. | ||||

| In the Linux kernel, the following vulnerability has been resolved: afs: Fix the setting of the server responding flag In afs_wait_for_operation(), we set transcribe the call responded flag to the server record that we used after doing the fileserver iteration loop - but it's possible to exit the loop having had a response from the server that we've discarded (e.g. it returned an abort or we started receiving data, but the call didn't complete). This means that op->server might be NULL, but we don't check that before attempting to set the server flag. | ||||

| In the Linux kernel, the following vulnerability has been resolved: cifs: Fix buffer overflow when parsing NFS reparse points ReparseDataLength is sum of the InodeType size and DataBuffer size. So to get DataBuffer size it is needed to subtract InodeType's size from ReparseDataLength. Function cifs_strndup_from_utf16() is currentlly accessing buf->DataBuffer at position after the end of the buffer because it does not subtract InodeType size from the length. Fix this problem and correctly subtract variable len. Member InodeType is present only when reparse buffer is large enough. Check for ReparseDataLength before accessing InodeType to prevent another invalid memory access. Major and minor rdev values are present also only when reparse buffer is large enough. Check for reparse buffer size before calling reparse_mkdev(). | ||||
| CVE-2024-49988 | 1 Linux | 1 Linux Kernel | 2026-08-04 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: add refcnt to ksmbd_conn struct When sending an oplock break request, opinfo->conn is used, But freed ->conn can be used on multichannel. This patch add a reference count to the ksmbd_conn struct so that it can be freed when it is no longer used. | ||||
| CVE-2024-49982 | 1 Linux | 1 Linux Kernel | 2026-08-04 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: aoe: fix the potential use-after-free problem in more places For fixing CVE-2023-6270, f98364e92662 ("aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts") makes tx() calling dev_put() instead of doing in aoecmd_cfg_pkts(). It avoids that the tx() runs into use-after-free. Then Nicolai Stange found more places in aoe have potential use-after-free problem with tx(). e.g. revalidate(), aoecmd_ata_rw(), resend(), probe() and aoecmd_cfg_rsp(). Those functions also use aoenet_xmit() to push packet to tx queue. So they should also use dev_hold() to increase the refcnt of skb->dev. On the other hand, moving dev_put() to tx() causes that the refcnt of skb->dev be reduced to a negative value, because corresponding dev_hold() are not called in revalidate(), aoecmd_ata_rw(), resend(), probe(), and aoecmd_cfg_rsp(). This patch fixed this issue. | ||||

| In the Linux kernel, the following vulnerability has been resolved: net: gso: fix tcp fraglist segmentation after pull from frag_list Detect tcp gso fraglist skbs with corrupted geometry (see below) and pass these to skb_segment instead of skb_segment_list, as the first can segment them correctly. Valid SKB_GSO_FRAGLIST skbs - consist of two or more segments - the head_skb holds the protocol headers plus first gso_size - one or more frag_list skbs hold exactly one segment - all but the last must be gso_size Optional datapath hooks such as NAT and BPF (bpf_skb_pull_data) can modify these skbs, breaking these invariants. In extreme cases they pull all data into skb linear. For TCP, this causes a NULL ptr deref in __tcpv4_gso_segment_list_csum at tcp_hdr(seg->next). Detect invalid geometry due to pull, by checking head_skb size. Don't just drop, as this may blackhole a destination. Convert to be able to pass to regular skb_segment. Approach and description based on a patch by Willem de Bruijn. | ||||

| CVE-2024-49965 | 1 Linux | 1 Linux Kernel | 2026-08-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ocfs2: remove unreasonable unlock in ocfs2_read_blocks Patch series "Misc fixes for ocfs2_read_blocks", v5. This series contains 2 fixes for ocfs2_read_blocks(). The first patch fix the issue reported by syzbot, which detects bad unlock balance in ocfs2_read_blocks(). The second patch fixes an issue reported by Heming Zhao when reviewing above fix. This patch (of 2): There was a lock release before exiting, so remove the unreasonable unlock. | ||||
| CVE-2024-49960 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2026-08-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ext4: fix timer use-after-free on failed mount Syzbot has found an ODEBUG bug in ext4_fill_super The del_timer_sync function cancels the s_err_report timer, which reminds about filesystem errors daily. We should guarantee the timer is no longer active before kfree(sbi). When filesystem mounting fails, the flow goes to failed_mount3, where an error occurs when ext4_stop_mmpd is called, causing a read I/O failure. This triggers the ext4_handle_error function that ultimately re-arms the timer, leaving the s_err_report timer active before kfree(sbi) is called. Fix the issue by canceling the s_err_report timer after calling ext4_stop_mmpd. | ||||

| In the Linux kernel, the following vulnerability has been resolved: ocfs2: reserve space for inline xattr before attaching reflink tree One of our customers reported a crash and a corrupted ocfs2 filesystem. The crash was due to the detection of corruption. Upon troubleshooting, the fsck -fn output showed the below corruption [EXTENT_LIST_FREE] Extent list in owner 33080590 claims 230 as the next free chain record, but fsck believes the largest valid value is 227. Clamp the next record value? n The stat output from the debugfs.ocfs2 showed the following corruption where the "Next Free Rec:" had overshot the "Count:" in the root metadata block.

The issue was in the reflink workfow while reserving space for inline xattr. The problematic function is ocfs2_reflink_xattr_inline(). By the time this function is called the reflink tree is already recreated at the destination inode from the source inode. At this point, this function reserves space for inline xattrs at the destination inode without even checking if there is space at the root metadata block. It simply reduces the l_count from 243 to 227 thereby making space of 256 bytes for inline xattr whereas the inode already has extents beyond this index (in this case up to 230), thereby causing corruption. The fix for this is to reserve space for inline metadata at the destination inode before the reflink tree gets recreated. The customer has verified the fix. | ||||

| In the Linux kernel, the following vulnerability has been resolved: gfs2: fix double destroy_workqueue error When gfs2_fill_super() fails, destroy_workqueue() is called within gfs2_gl_hash_clear(), and the subsequent code path calls destroy_workqueue() on the same work queue again. This issue can be fixed by setting the work queue pointer to NULL after the first destroy_workqueue() call and checking for a NULL pointer before attempting to destroy the work queue again. | ||||

| In the Linux kernel, the following vulnerability has been resolved: drm/xe/guc_submit: add missing locking in wedged_fini Any non-wedged queue can have a zero refcount here and can be running concurrently with an async queue destroy, therefore dereferencing the queue ptr to check wedge status after the lookup can trigger UAF if queue is not wedged. Fix this by keeping the submission_state lock held around the check to postpone the free and make the check safe, before dropping again around the put() to avoid the deadlock.

| CVE-2024-49940 | 1 Linux | 1 Linux Kernel | 2026-08-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: l2tp: prevent possible tunnel refcount underflow When a session is created, it sets a backpointer to its tunnel. When the session refcount drops to 0, l2tp_session_free drops the tunnel refcount if session->tunnel is non-NULL. However, session->tunnel is set in l2tp_session_create, before the tunnel refcount is incremented by l2tp_session_register, which leaves a small window where session->tunnel is non-NULL when the tunnel refcount hasn't been bumped. Moving the assignment to l2tp_session_register is trivial but l2tp_session_create calls l2tp_session_set_header_len which uses session->tunnel to get the tunnel's encap. Add an encap arg to l2tp_session_set_header_len to avoid using session->tunnel. If l2tpv3 sessions have colliding IDs, it is possible for l2tp_v3_session_get to race with l2tp_session_register and fetch a session which doesn't yet have session->tunnel set. Add a check for this case. | ||||

Therefore, we have added a check to prevent double adding of the list. list_add double add: new=ffff99d6992e2010, prev=ffff99d6992e2010, next=ffff99d695302628. ------------[ cut here ]------------ kernel BUG at lib/list_debug.c:37! invalid opcode: 0000 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 9 Comm: kworker/0:1 Tainted: G W O 6.6.30-02659-gc18865c4dfbd #1 770df2933251a0e3c888ba69d1053a817a6376a7 Hardware name: HP Grunt/Grunt, BIOS Google_Grunt.11031.169.0 06/24/2021 Workqueue: events_freezable ieee80211_restart_work [mac80211] RIP: 0010:__list_add_valid_or_report+0x5e/0xb0 Code: c7 74 18 48 39 ce 74 13 b0 01 59 5a 5e 5f 41 58 41 59 41 5a 5d e9 e2 d6 03 00 cc 48 c7 c7 8d 4f 17 83 48 89 c2 e8 02 c0 00 00 <0f> 0b 48 c7 c7 aa 8c 1c 83 e8 f4 bf 00 00 0f 0b 48 c7 c7 c8 bc 12 RSP: 0018:ffffa91b8007bc50 EFLAGS: 00010246 RAX: 0000000000000058 RBX: ffff99d6992e0900 RCX: a014d76c70ef3900 RDX: ffffa91b8007bae8 RSI: 00000000ffffdfff RDI: 0000000000000001 RBP: ffffa91b8007bc88 R08: 0000000000000000 R09: ffffa91b8007bae0 R10: 00000000ffffdfff R11: ffffffff83a79800 R12: ffff99d695302060 R13: ffff99d695300900 R14: ffff99d6992e1be0 R15: ffff99d6992e2010 FS: 0000000000000000(0000) GS:ffff99d6aac00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000078fbdba43480 CR3: 000000010e464000 CR4: 00000000001506f0 Call Trace: <TASK> ? __die_body+0x1f/0x70 ? die+0x3d/0x60 ? do_trap+0xa4/0x110 ? __list_add_valid_or_report+0x5e/0xb0 ? do_error_trap+0x6d/0x90 ? __list_add_valid_or_report+0x5e/0xb0 ? handle_invalid_op+0x30/0x40 ? __list_add_valid_or_report+0x5e/0xb0 ? exc_invalid_op+0x3c/0x50 ? asm_exc_invalid_op+0x16/0x20 ? __list_add_valid_or_report+0x5e/0xb0 rtw89_ops_add_interface+0x309/0x310 [rtw89_core 7c32b1ee6854761c0321027c8a58c5160e41f48f] drv_add_interface+0x5c/0x130 [mac80211 83e989e6e616bd5b4b8a2b0a9f9352a2c385a3bc] ieee80211_reconfig+0x241/0x13d0 [mac80211 83e989e6e616bd5b4b8a2b0a9f9352a2c385a3bc] ? finish_wait+0x3e/0x90 ? synchronize_rcu_expedited+0x174/0x260 ? sync_rcu_exp_done_unlocked+0x50/0x50 ? wake_bit_function+0x40/0x40 ieee80211_restart_work+0xf0/0x140 [mac80211 83e989e6e616bd5b4b8a2b0a9f9352a2c385a3bc] process_scheduled_works+0x1e5/0x480 worker_thread+0xea/0x1e0 kthread+0xdb/0x110 ? move_linked_works+0x90/0x90 ? kthread_associate_blkcg+0xa0/0xa0 ret_from_fork+0x3b/0x50 ? kthread_associate_blkcg+0xa0/0xa0 ret_from_fork_asm+0x11/0x20 </TASK> Modules linked in: dm_integrity async_xor xor async_tx lz4 lz4_compress zstd zstd_compress zram zsmalloc rfcomm cmac uinput algif_hash algif_skcipher af_alg btusb btrtl iio_trig_hrtimer industrialio_sw_trigger btmtk industrialio_configfs btbcm btintel uvcvideo videobuf2_vmalloc iio_trig_sysfs videobuf2_memops videobuf2_v4l2 videobuf2_common uvc snd_hda_codec_hdmi veth snd_hda_intel snd_intel_dspcfg acpi_als snd_hda_codec industrialio_triggered_buffer kfifo_buf snd_hwdep industrialio i2c_piix4 snd_hda_core designware_i2s ip6table_nat snd_soc_max98357a xt_MASQUERADE xt_cgroup snd_soc_acp_rt5682_mach fuse rtw89_8922ae(O) rtw89_8922a(O) rtw89_pci(O) rtw89_core(O) 8021q mac80211(O) bluetooth ecdh_generic ecc cfg80211 r8152 mii joydev gsmi: Log Shutdown Reason 0x03 ---[ end trace 0000000000000000 ]--- | ||||
| CVE-2024-49936 | 1 Linux | 1 Linux Kernel | 2026-08-04 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: net/xen-netback: prevent UAF in xenvif_flush_hash() During the list_for_each_entry_rcu iteration call of xenvif_flush_hash, kfree_rcu does not exist inside the rcu read critical section, so if kfree_rcu is called when the rcu grace period ends during the iteration, UAF occurs when accessing head->next after the entry becomes free. Therefore, to solve this, you need to change it to list_for_each_entry_safe. | ||||
