CVE-2024-35810 (GCVE-0-2024-35810)
Vulnerability from cvelistv5
Published

Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fix the lifetime of the bo cursor memory The cleanup can be dispatched while the atomic update is still active, which means that the memory acquired in the atomic update needs to not be invalidated by the cleanup. The buffer objects in vmw_plane_state instead of using the builtin map_and_cache were trying to handle the lifetime of the mapped memory themselves, leading to crashes. Use the map_and_cache instead of trying to manage the lifetime of the buffer objects held by the vmw_plane_state. Fixes kernel oops'es in IGT's kms_cursor_legacy forked-bo.

No root or CAP_SYS_ADMIN is needed.\\nUI:N - The attacker\u0027s own processes issue all the cursor ioctls that create and win the race; no action by any other user is required.\\nS:U - The corrupted mappings and buffer objects are all guest-kernel memory managed by the same vmwgfx/TTM authority; there is no guest-to-host escape or IOMMU boundary crossing.\\nC:H - After the concurrent ttm_bo_kunmap()/vunmap(), the vmalloc VA range can be reused by other kernel subsystems (kernel stacks, modules, BPF), and the stale pointer is then read by memcmp() and by memcpy(header + 1, image, image_size) into the cursor MOB that gets rendered as the visible cursor \\u2014 a use-after-unmap read that discloses recycled kernel memory.\\nI:H - This is a use-after-free/use-after-unmap class bug: racing kmap/kunmap on the shared vmw_bo-\u003emap allows double-vunmap of a VA that another subsystem may have re-mapped, and the concurrent cursor-MOB swap/put lets vmw_cursor_update_mob() memcpy into a buffer object that has been returned to the cache or freed, giving heap-spray and write primitives.\\nA:H - The commit explicitly states it \\\"Fixes kernel oops\u0027es in IGT\u0027s kms_cursor_legacy forked-bo\\\"; dereferencing the vunmap\u0027d address faults in kernel context, and ttm_bo_kunmap()\u0027s default case is a BUG(), so the race yields a reliable kernel crash.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"bb6780aa5a1d99e86757c0c96bfae65a46cf839e\", \"lessThan\": \"86cb706a40b7e6b2221ee49a298a65ad9b46c02d\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bb6780aa5a1d99e86757c0c96bfae65a46cf839e\", \"lessThan\": \"104a5b2772bc7c0715ae7355ccf9d294a472765c\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bb6780aa5a1d99e86757c0c96bfae65a46cf839e\", \"lessThan\": \"ed381800ea6d9a4c7f199235a471c0c48100f0ae\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bb6780aa5a1d99e86757c0c96bfae65a46cf839e\", \"lessThan\": \"9a9e8a7159ca09af9b1a300a6c8e8b6ff7501c76\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/gpu/drm/vmwgfx/vmwgfx_kms.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6.2\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"6.2\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.6.24\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.7.12\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.7.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8.3\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.8.*\"}, {\"status\": \"unaffected\", \"version\": \"6.9\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/gpu/drm/vmwgfx/vmwgfx_kms.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/86cb706a40b7e6b2221ee49a298a65ad9b46c02d\"}, {\"url\": \"https://git.kernel.org/stable/c/104a5b2772bc7c0715ae7355ccf9d294a472765c\"}, {\"url\": \"https://git.kernel.org/stable/c/ed381800ea6d9a4c7f199235a471c0c48100f0ae\"}, {\"url\": \"https://git.kernel.org/stable/c/9a9e8a7159ca09af9b1a300a6c8e8b6ff7501c76\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ndrm/vmwgfx: Fix the lifetime of the bo cursor memory\\n\\nThe cleanup can be dispatched while the atomic update is still active,\\nwhich means that the memory acquired in the atomic update needs to\\nnot be invalidated by the cleanup.
