No network or remote data path reaches this code.\nAC:L - Once the driver has probe-failed on the reset line, the stale notifier remains on the global v4l2 notifier_list indefinitely, and any subsequent subdev registration deterministically walks the freed object; no race or unpredictable memory layout must be won to reach the freed dereference.\nPR:L - A local user account on the device is sufficient to interact with the media/V4L2 stack and trigger subdev registration paths that walk the corrupted global notifier list; no root or administrative capability is needed to consume the dangling pointer.\nUI:N - The stale notifier is left behind automatically by the failing probe path and is dereferenced by kernel-internal V4L2 async registration; no victim action such as opening a file or mounting a filesystem is required.\nS:U - The freed memory, the corrupted list, and the resulting impact are all within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The devm-allocated stm32_dcmi object containing the notifier is freed while still linked into the global notifier_list, so reallocated heap contents are read back as notifier state and traversed as list pointers, which can be leveraged to disclose kernel memory.\nI:H - Traversal and eventual list_del of the freed notifier_entry performs writes through attacker-influenceable heap contents, giving a use-after-free list-corruption primitive that can be shaped into an arbitrary write and control-flow hijack.\nA:H - Dereferencing and unlinking a freed notifier from the global list reliably produces list corruption and an oops or panic in the V4L2 async core, taking down the kernel."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/media/platform/st/stm32/stm32-dcmi.c"], "versions": [{"version": "d079f94c90469f413920b9f2b201537fac2ceb06", "lessThan": "222a9301b086852b90d3b092fef436c3f4e927c4", "status": "affected", "versionType": "git"}, {"version": "d079f94c90469f413920b9f2b201537fac2ceb06", "lessThan": "37ff63c5d7119cbc5c6bacdcc658add6008a8e1f", "status": "affected", "versionType": "git"}, {"version": "d079f94c90469f413920b9f2b201537fac2ceb06", "lessThan": "6c6f22b7e6cbc4e8c1e359fc9b190419391c3db7", "status": "affected", "versionType": "git"}, {"version": "d079f94c90469f413920b9f2b201537fac2ceb06", "lessThan": "931abe1deb65b919d23fa203d7f6d6fbd4fccd8e", "status": "affected", "versionType": "git"}, {"version": "d079f94c90469f413920b9f2b201537fac2ceb06", "lessThan": "4b7ee504969e074725e439c949f2483e5fa5572a", "status": "affected", "versionType": "git"}, {"version": "d079f94c90469f413920b9f2b201537fac2ceb06", "lessThan": "084973ebd67b28f0945c5d45408f86c58b540110", "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/st/stm32/stm32-dcmi.c"], "versions": [{"version": "4.20", "status": "affected"}, {"version": "0", "lessThan": "4.20", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.183", "lessThanOrEqual": "6.1.*", "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", "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": "4.20", "versionEndExcluding": "6.1.183"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "6.6.148"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "6.12.101"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "6.18.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "7.1.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.20", "versionEndExcluding": "7.2"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/222a9301b086852b90d3b092fef436c3f4e927c4"}, {"url": "https://git.kernel.org/stable/c/37ff63c5d7119cbc5c6bacdcc658add6008a8e1f"}, {"url": "https://git.kernel.org/stable/c/6c6f22b7e6cbc4e8c1e359fc9b190419391c3db7"}, {"url": "https://git.kernel.org/stable/c/931abe1deb65b919d23fa203d7f6d6fbd4fccd8e"}, {"url": "https://git.kernel.org/stable/c/4b7ee504969e074725e439c949f2483e5fa5572a"}, {"url": "https://git.kernel.org/stable/c/084973ebd67b28f0945c5d45408f86c58b540110"}], "title": "media: stm32: dcmi: unregister notifier on probe failure", "x_generator": {"engine": "bippy-1.2.0"}}}}
