CVSS: 6.3EPSS: 0%CPEs: 9EXPL: 0CVE-2024-26880 – dm: call the resume method on internal suspend
https://notcve.org/view.php?id=CVE-2024-26880
In the Linux kernel, the following vulnerability has been resolved: dm: call the resume method on internal suspend There is this reported crash when experimenting with the lvm2 testsuite. The list corruption is caused by the fact that the postsuspend and resume methods were not paired correctly; there were two consecutive calls to the origin_postsuspend function. The second call attempts to remove the "hash_list" entry from a list, while it was already removed by the first call. Fix __dm_internal_resume so that it calls the preresume and resume methods of the table's targets. If a preresume method of some target fails, we are in a tricky situation. We can't return an error because dm_internal_resume isn't supposed to return errors. We can't return success, because then the "resume" and "postsuspend" methods would not be paired correctly. So, we set the DMF_SUSPENDED flag and we fake normal suspend - it may confuse userspace tools, but it won't cause a kernel crash. ------------[ cut here ]------------ kernel BUG at lib/list_debug.c:56! invalid opcode: 0000 [#1] PREEMPT SMP CPU: 1 PID: 8343 Comm: dmsetup Not tainted 6.8.0-rc6 #4 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014 RIP: 0010:__list_del_entry_valid_or_report+0x77/0xc0 <snip> RSP: 0018:ffff8881b831bcc0 EFLAGS: 00010282 RAX: 000000000000004e RBX: ffff888143b6eb80 RCX: 0000000000000000 RDX: 0000000000000001 RSI: ffffffff819053d0 RDI: 00000000ffffffff RBP: ffff8881b83a3400 R08: 00000000fffeffff R09: 0000000000000058 R10: 0000000000000000 R11: ffffffff81a24080 R12: 0000000000000001 R13: ffff88814538e000 R14: ffff888143bc6dc0 R15: ffffffffa02e4bb0 FS: 00000000f7c0f780(0000) GS:ffff8893f0a40000(0000) knlGS:0000000000000000 CS: 0010 DS: 002b ES: 002b CR0: 0000000080050033 CR2: 0000000057fb5000 CR3: 0000000143474000 CR4: 00000000000006b0 Call Trace: <TASK> ? • https://git.kernel.org/stable/c/ffcc39364160663cda1a3c358f4537302a92459b https://git.kernel.org/stable/c/69836d9329f0b4c58faaf3d886a7748ddb5bf718 https://git.kernel.org/stable/c/da7ece2197101b1469853e6b5e915be1e3896d52 https://git.kernel.org/stable/c/f89bd27709376d37ff883067193320c58a8c1d5a https://git.kernel.org/stable/c/03ad5ad53e51abf3a4c7538c1bc67a5982b41dc5 https://git.kernel.org/stable/c/ad10289f68f45649816cc68eb93f45fd5ec48a15 https://git.kernel.org/stable/c/15a3fc5c8774c17589dabfe1d642d40685c985af https://git.kernel.org/stable/c/ef02d8edf738557af2865c5bfb66a03c4 • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') •

https://notcve.org/view.php?id=CVE-2024-26874
In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Fix a null pointer crash in mtk_drm_crtc_finish_page_flip It's possible that mtk_crtc->event is NULL in mtk_drm_crtc_finish_page_flip(). pending_needs_vblank value is set by mtk_crtc->event, but in mtk_drm_crtc_atomic_flush(), it's is not guarded by the same lock in mtk_drm_finish_page_flip(), thus a race condition happens. Consider the following case: CPU1 CPU2 step 1: mtk_drm_crtc_atomic_begin() mtk_crtc->event is not null, step 1: mtk_drm_crtc_atomic_flush: mtk_drm_crtc_update_config( !!mtk_crtc->event) step 2: mtk_crtc_ddp_irq -> mtk_drm_finish_page_flip: lock mtk_crtc->event set to null, pending_needs_vblank set to false unlock pending_needs_vblank set to true, step 2: mtk_crtc_ddp_irq -> mtk_drm_finish_page_flip called again, pending_needs_vblank is still true //null pointer Instead of guarding the entire mtk_drm_crtc_atomic_flush(), it's more efficient to just check if mtk_crtc->event is null before use. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/mediatek: corrige un fallo del puntero nulo en mtk_drm_crtc_finish_page_flip Es posible que mtk_crtc->event sea NULL en mtk_drm_crtc_finish_page_flip(). El valor pendiente_needs_vblank lo establece mtk_crtc->event, pero en mtk_drm_crtc_atomic_flush(), no está protegido por el mismo bloqueo en mtk_drm_finish_page_flip(), por lo que ocurre una condición de carrera. Considere el siguiente caso: CPU1 CPU2 paso 1: mtk_drm_crtc_atomic_begin() mtk_crtc->event is not null, paso 1: mtk_drm_crtc_atomic_flush: mtk_drm_crtc_update_config( !! • https://git.kernel.org/stable/c/119f5173628aa7a0c3cf9db83460d40709e8241d https://git.kernel.org/stable/c/accdac6b71d5a2b84040c3d2234f53a60edc398e https://git.kernel.org/stable/c/dfde84cc6c589f2a9f820f12426d97365670b731 https://git.kernel.org/stable/c/4688be96d20ffa49d2186523ee84f475f316fd49 https://git.kernel.org/stable/c/9beec711a17245b853d64488fd5b739031612340 https://git.kernel.org/stable/c/d2bd30c710475b2e29288827d2c91f9e6e2b91d7 https://git.kernel.org/stable/c/a3dd12b64ae8373a41a216a0b621df224210860a https://git.kernel.org/stable/c/9acee29a38b4d4b70f1f583e5ef9a245d •
