If a device returns an\nentry without a terminating NUL byte, strlen() reads past the end of\nthe slot and can run beyond the allocated buffer, triggering an\nout-of-bounds read.\n\nValidate that each returned TV mode name contains a NUL terminator\nwithin its fixed-size slot before passing it to the DRM property code.\nIf a malformed entry is found, reject the device response with -EIO.\n\nThis fixes the out-of-bounds read without changing the handling of\nvalid devices, and avoids silently truncating malformed protocol data." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/gpu/drm/gud/gud_connector.c" ], "versions": [ { "version": "40e1a70b4aedf2859a1829991b48ef0ebe650bf2", "lessThan": "676f1fb3632bbc9ce83be7938e93fe6bfc9510fd", "status": "affected", "versionType": "git" }, { "version": "40e1a70b4aedf2859a1829991b48ef0ebe650bf2", "lessThan": "06fcaf21c18ac88f57fee3803554f48c6026b95f", "status": "affected", "versionType": "git" }, { "version": "40e1a70b4aedf2859a1829991b48ef0ebe650bf2", "lessThan": "082e378886547b5b1c4075ed307f7c68547868dc", "status": "affected", "versionType": "git" }, { "version": "40e1a70b4aedf2859a1829991b48ef0ebe650bf2", "lessThan": "70cffc31a380b3eae45027101647aa94c242aa0e", "status": "affected", "versionType": "git" }, { "version": "40e1a70b4aedf2859a1829991b48ef0ebe650bf2", "lessThan": "72a95df6bbc7d20c7af1e39d86b3e910cccd01ad", "status": "affected", "versionType": "git" }, { "version": "40e1a70b4aedf2859a1829991b48ef0ebe650bf2", "lessThan": "eab46d9629807db1b5647d17227e16110a18227f", "status": "affected", "versionType": "git" }, { "version": "40e1a70b4aedf2859a1829991b48ef0ebe650bf2", "lessThan": "da1ea35fea67ad841f4ada28dd61b41be65e5437", "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/gud/gud_connector.c" ], "versions": [ { "version": "5.13", "status": "affected" }, { "version": "0", "lessThan": "5.13", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.221", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.188", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.157", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.110", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.18.51", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.2.5", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.3", "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": "5.15.221" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "6.1.188" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "6.6.157" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "6.12.110" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "6.18.51" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "7.2.5" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13", "versionEndExcluding": "7.3" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/676f1fb3632bbc9ce83be7938e93fe6bfc9510fd" }, { "url": "https://git.kernel.org/stable/c/06fcaf21c18ac88f57fee3803554f48c6026b95f" }, { "url": "https://git.kernel.org/stable/c/082e378886547b5b1c4075ed307f7c68547868dc" }, { "url": "https://git.kernel.org/stable/c/70cffc31a380b3eae45027101647aa94c242aa0e" }, { "url": "https://git.kernel.org/stable/c/72a95df6bbc7d20c7af1e39d86b3e910cccd01ad" }, { "url": "https://git.kernel.org/stable/c/eab46d9629807db1b5647d17227e16110a18227f" }, { "url": "https://git.kernel.org/stable/c/da1ea35fea67ad841f4ada28dd61b41be65e5437" } ], "title": "drm/gud: validate TV mode names before creating enum property", "x_generator": { "engine": "bippy-1.2.0" } } } }
