This was\nmodified to handle the specific case of -ENXIO separately, allowing the\nfunction to proceed without logging the error in this case. However,\nthis change unintentionally left a path where md_autodetect_dev()\ncould be called without confirming that part is a valid pointer.\n\nThis commit separates the error handling logic by splitting the\ninitial if-condition, improving code readability and handling specific\nerror scenarios explicitly. The function now distinguishes the general\nerror case from -ENXIO without altering the existing behavior of\nmd_autodetect_dev() calls."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["block/partitions/core.c"],"versions":[{"version":"b72053072c0bbe9f1cdfe2ffa3c201c185da2201","lessThan":"4bc4272e2506941c3f3d4fb8b0c659ee814dcf6f","status":"affected","versionType":"git"},{"version":"b72053072c0bbe9f1cdfe2ffa3c201c185da2201","lessThan":"cc4d21d9492db4e534d3e01253cf885c90dd2a8b","status":"affected","versionType":"git"},{"version":"b72053072c0bbe9f1cdfe2ffa3c201c185da2201","lessThan":"64cf2a39202ca2d9df5ee70eb310b6141ce2b8ed","status":"affected","versionType":"git"},{"version":"b72053072c0bbe9f1cdfe2ffa3c201c185da2201","lessThan":"80f5bfbb80ea1615290dbc24f49d3d8c86db58fe","status":"affected","versionType":"git"},{"version":"b72053072c0bbe9f1cdfe2ffa3c201c185da2201","lessThan":"652039ba477c9a4ab43740cf2cb0d068d53508c2","status":"affected","versionType":"git"},{"version":"b72053072c0bbe9f1cdfe2ffa3c201c185da2201","lessThan":"afe53ea9b378c376101d99d216f13b6256f75189","status":"affected","versionType":"git"},{"version":"b72053072c0bbe9f1cdfe2ffa3c201c185da2201","lessThan":"26e197b7f9240a4ac301dd0ad520c0c697c2ea7d","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["block/partitions/core.c"],"versions":[{"version":"5.5","status":"affected"},{"version":"0","lessThan":"5.5","status":"unaffected","versionType":"semver"},{"version":"5.10.227","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.168","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.113","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.54","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.10.13","lessThanOrEqual":"6.10.*","status":"unaffected","versionType":"semver"},{"version":"6.11.2","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12","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":"5.5","versionEndExcluding":"5.10.227"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"5.15.168"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.1.113"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.6.54"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.10.13"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.11.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/4bc4272e2506941c3f3d4fb8b0c659ee814dcf6f"},{"url":"https://git.kernel.org/stable/c/cc4d21d9492db4e534d3e01253cf885c90dd2a8b"},{"url":"https://git.kernel.org/stable/c/64cf2a39202ca2d9df5ee70eb310b6141ce2b8ed"},{"url":"https://git.kernel.org/stable/c/80f5bfbb80ea1615290dbc24f49d3d8c86db58fe"},{"url":"https://git.kernel.org/stable/c/652039ba477c9a4ab43740cf2cb0d068d53508c2"},{"url":"https://git.kernel.org/stable/c/afe53ea9b378c376101d99d216f13b6256f75189"},{"url":"https://git.kernel.org/stable/c/26e197b7f9240a4ac301dd0ad520c0c697c2ea7d"}],"title":"block: fix potential invalid pointer dereference in blk_add_partition","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-47705","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-10-21T13:04:01.361907Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-10-21T13:04:19.823Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T22:21:08.827Z"}}]}}
