If the VBIOS reports a structuresize larger than\nthe actual mapped data, the loop reads past the end of the BIOS image,\ncausing an out-of-bounds read.\n\nFix this by calling bios_get_image() to validate that the full claimed\nstructuresize is accessible within the BIOS image before entering the\nloop in both functions.\n\n(cherry picked from commit ba5e95b43b773ae1bf1f66ee6b31eb774e65afe3)"}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 7.8, "baseSeverity": "HIGH"}}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/gpu/drm/amd/display/dc/bios/bios_parser2.c"], "versions": [{"version": "ae79c310b1a6f97429a5784b65f125d9cc9c95b1", "lessThan": "9900f6954be779011e7c2cd42addd87baf028bc5", "status": "affected", "versionType": "git"}, {"version": "ae79c310b1a6f97429a5784b65f125d9cc9c95b1", "lessThan": "fb30a3890d62fd50a95aef684faf64a307592e42", "status": "affected", "versionType": "git"}, {"version": "ae79c310b1a6f97429a5784b65f125d9cc9c95b1", "lessThan": "67461e0c15335894cc5d3b84cda823bf8cbdc886", "status": "affected", "versionType": "git"}, {"version": "ae79c310b1a6f97429a5784b65f125d9cc9c95b1", "lessThan": "7ca695b3122297b06a3ed605bbe1cd32c85d9f5a", "status": "affected", "versionType": "git"}, {"version": "ae79c310b1a6f97429a5784b65f125d9cc9c95b1", "lessThan": "f2a4827e980ba07de4391fa84d9c39a12726bdd7", "status": "affected", "versionType": "git"}, {"version": "ae79c310b1a6f97429a5784b65f125d9cc9c95b1", "lessThan": "86d2b20644b11d21fe52c596e6e922b4590a3e3f", "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/gpu/drm/amd/display/dc/bios/bios_parser2.c"], "versions": [{"version": "4.15", "status": "affected"}, {"version": "0", "lessThan": "4.15", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.175", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.142", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.92", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.34", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.11", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1", "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": "4.15", "versionEndExcluding": "6.1.175"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.15", "versionEndExcluding": "6.6.142"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.15", "versionEndExcluding": "6.12.92"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.15", "versionEndExcluding": "6.18.34"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.15", "versionEndExcluding": "7.0.11"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.15", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/9900f6954be779011e7c2cd42addd87baf028bc5"}, {"url": "https://git.kernel.org/stable/c/fb30a3890d62fd50a95aef684faf64a307592e42"}, {"url": "https://git.kernel.org/stable/c/67461e0c15335894cc5d3b84cda823bf8cbdc886"}, {"url": "https://git.kernel.org/stable/c/7ca695b3122297b06a3ed605bbe1cd32c85d9f5a"}, {"url": "https://git.kernel.org/stable/c/f2a4827e980ba07de4391fa84d9c39a12726bdd7"}, {"url": "https://git.kernel.org/stable/c/86d2b20644b11d21fe52c596e6e922b4590a3e3f"}], "title": "drm/amd/display: Validate GPIO pin LUT table size before iterating", "x_generator": {"engine": "bippy-1.2.0"}}}}
