It is not reachable from network packets or physical bus traffic.\nAC:L - An attacker who can open the decoder can reliably set jpeg_parse_error (malformed JPEG in buf_queue, or capture/output plane mismatch) while ctx->slot is still MXC_MAX_SLOTS, causing a deterministic out-of-bounds write with no race or uncontrollable condition.\nPR:L - The driver has no capability checks; V4L2 nodes are group video with uaccess, and on typical i.MX/Android deployments unprivileged apps can use the JPEG codec. Real root is not required.\nUI:N - The attacker opens the device and queues buffers themselves; no separate victim action is needed to hit the parse-error path.\nS:U - The OOB write corrupts fields in the same kernel mxc_jpeg_dev object and does not cross a VM, IOMMU, or other security-authority boundary.\nC:N - The bug is a write-only store of a fixed false/0 into the byte overlapping num_domains; there is no out-of-bounds read or other disclosure primitive.\nI:H - Accessing slot_data[MXC_MAX_SLOTS].used is an out-of-bounds write into adjacent kernel memory (num_domains). Per kernel CVSS guidance, out-of-bounds writes are scored High.\nA:H - Corrupting num_domains skips PM-domain detach on rmmod and the fix commit documents a resulting kernel panic on re-insmod; kernel crash/panic is High availability impact."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/media/platform/imx-jpeg/mxc-jpeg.c"], "versions": [{"version": "2db16c6ed72ce644d5639b3ed15e5817442db4ba", "lessThan": "02f9f97d54ffc85b50ad77f5b1f3c8f69cd17747", "status": "affected", "versionType": "git"}, {"version": "2db16c6ed72ce644d5639b3ed15e5817442db4ba", "lessThan": "20c8b90430c5d6c4a3936eaa7c35aac670581487", "status": "affected", "versionType": "git"}, {"version": "2db16c6ed72ce644d5639b3ed15e5817442db4ba", "lessThan": "e209e6db2e527db6a93b14c2deedf969caca78fc", "status": "affected", "versionType": "git"}, {"version": "2db16c6ed72ce644d5639b3ed15e5817442db4ba", "lessThan": "97558d170a1236280407e8d29a7d095d2c2ed554", "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/media/platform/imx-jpeg/mxc-jpeg.c"], "versions": [{"version": "5.13", "status": "affected"}, {"version": "0", "lessThan": "5.13", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.33", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.16.19", "lessThanOrEqual": "5.16.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.17.2", "lessThanOrEqual": "5.17.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.18", "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": "5.13", "versionEndExcluding": "5.15.33"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "5.16.19"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "5.17.2"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "5.18"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/02f9f97d54ffc85b50ad77f5b1f3c8f69cd17747"}, {"url": "https://git.kernel.org/stable/c/20c8b90430c5d6c4a3936eaa7c35aac670581487"}, {"url": "https://git.kernel.org/stable/c/e209e6db2e527db6a93b14c2deedf969caca78fc"}, {"url": "https://git.kernel.org/stable/c/97558d170a1236280407e8d29a7d095d2c2ed554"}], "title": "media: imx-jpeg: fix a bug of accessing array out of bounds", "x_generator": {"engine": "bippy-1.2.0"}}}}
