There is no remote or network-facing path to the stateless H.264 decoder.\nAC:L - The attacker fully and deterministically controls the out-of-range value: ref_pic_list0/1[i].index is a u8 copied verbatim from the control payload with no validation, so any index in 16..255 immediately produces the out-of-bounds dpb[] access on the next decode run. No race, timing, or uncontrollable memory-layout condition is involved.\nPR:L - Only an unprivileged local account with access to the cedrus video device node is needed (typically the 'video' group, or the media/camera service on Android and embedded Allwinner devices). No capability, CAP_SYS_ADMIN, or root check exists anywhere on the path \u2014 cedrus_try_ctrl() validates only SPS chroma format and bit depth.\nUI:N - The attacking process performs the entire sequence itself \u2014 open the device, set the crafted H.264 slice-params control, queue buffers, start streaming. No victim action, file open, or media mount is required.\nS:U - The out-of-bounds read stays within the kernel's own memory and security authority; no VM, IOMMU, or sandbox boundary is crossed. This is a standard in-kernel driver memory-safety defect.\nC:H - decode->dpb[] holds 16 32-byte entries at the start of a ~560-byte control allocation, so an attacker-chosen index up to 255 reads at offset 8160 \u2014 about 7.6 KB of adjacent kernel heap beyond the object. The read flags/reference_ts values are consumed by the ACTIVE test and vb2_find_buffer() timestamp lookup, giving an attacker-steerable oracle over unrelated kernel heap contents.\nI:N - The defect is purely a read: num_ref is bounded to V4L2_H264_REF_LIST_LEN by v4l2-ctrls-core.c, so the sram_array[CEDRUS_MAX_REF_IDX] stores stay in bounds, and only a legitimately-looked-up buffer position is written to hardware SRAM. No kernel memory is modified out of bounds.\nA:H - Reading several kilobytes past the end of a slab object can walk off the slab page into an unmapped or poisoned region, and trips KASAN/hardening checks, producing a kernel oops. The trigger is trivially repeatable from an unprivileged process, so the crash can be induced at will."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/staging/media/sunxi/cedrus/cedrus_h264.c"], "versions": [{"version": "e000e1fa4bdbd783149e7f97cf3be61e1c0bab8c", "lessThan": "2ee8327c85b3ac7b532d2d6a1e3a295d5ad7414a", "status": "affected", "versionType": "git"}, {"version": "e000e1fa4bdbd783149e7f97cf3be61e1c0bab8c", "lessThan": "0af8945fcae742d099f59f3c725eb67235953a31", "status": "affected", "versionType": "git"}, {"version": "e000e1fa4bdbd783149e7f97cf3be61e1c0bab8c", "lessThan": "9924cb548ee7753a6473997949c3ec48092de0b0", "status": "affected", "versionType": "git"}, {"version": "e000e1fa4bdbd783149e7f97cf3be61e1c0bab8c", "lessThan": "e53112c2de88982e66c369aee2120d5efd78df30", "status": "affected", "versionType": "git"}, {"version": "e000e1fa4bdbd783149e7f97cf3be61e1c0bab8c", "lessThan": "10358ea986c3c85516d1c8206486464f79d36e76", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/staging/media/sunxi/cedrus/cedrus_h264.c"], "versions": [{"version": "5.10", "status": "affected"}, {"version": "0", "lessThan": "5.10", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.148", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.101", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.42", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.6", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2-rc1", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.10", "versionEndExcluding": "6.6.148"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.10", "versionEndExcluding": "6.12.101"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.10", "versionEndExcluding": "6.18.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.10", "versionEndExcluding": "7.1.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.10", "versionEndExcluding": "7.2-rc1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/2ee8327c85b3ac7b532d2d6a1e3a295d5ad7414a"}, {"url": "https://git.kernel.org/stable/c/0af8945fcae742d099f59f3c725eb67235953a31"}, {"url": "https://git.kernel.org/stable/c/9924cb548ee7753a6473997949c3ec48092de0b0"}, {"url": "https://git.kernel.org/stable/c/e53112c2de88982e66c369aee2120d5efd78df30"}, {"url": "https://git.kernel.org/stable/c/10358ea986c3c85516d1c8206486464f79d36e76"}], "title": "media: cedrus: skip invalid H.264 reference list entries", "x_generator": {"engine": "bippy-1.2.0"}}}}
