Async\nconnections are zero-allocated, so the list entry still has NULL next\nand prev pointers on this path. Calling list_del() on it can therefore\ndereference NULL instead of returning the original link creation error.\n\nDo not delete asc_subdev_entry from err_call_unbind. There is no list\ninsertion to undo on this path; the bound callback and sub-device\nregistration are the operations that need to be rolled back."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/media/v4l2-core/v4l2-async.c"],"versions":[{"version":"28a1295795d85a25f2e7dd391c43969e95fcb341","lessThan":"d273571e531405426983c6a45ec635c7d0415eed","status":"affected","versionType":"git"},{"version":"28a1295795d85a25f2e7dd391c43969e95fcb341","lessThan":"caac13f518d83974e9884d1eeda3d4cc3bb92978","status":"affected","versionType":"git"},{"version":"28a1295795d85a25f2e7dd391c43969e95fcb341","lessThan":"3345746e0957bce6c53644838e4955710a82a962","status":"affected","versionType":"git"},{"version":"28a1295795d85a25f2e7dd391c43969e95fcb341","lessThan":"a57d94026cb4fd7b3d258f0db2ad391cbccfaba5","status":"affected","versionType":"git"},{"version":"28a1295795d85a25f2e7dd391c43969e95fcb341","lessThan":"47d82b605351c0e04f6365e42c8ffe2fcfdba615","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/v4l2-core/v4l2-async.c"],"versions":[{"version":"6.6","status":"affected"},{"version":"0","lessThan":"6.6","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-rc1","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":"6.6","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6","versionEndExcluding":"6.18.51"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6","versionEndExcluding":"7.2.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/d273571e531405426983c6a45ec635c7d0415eed"},{"url":"https://git.kernel.org/stable/c/caac13f518d83974e9884d1eeda3d4cc3bb92978"},{"url":"https://git.kernel.org/stable/c/3345746e0957bce6c53644838e4955710a82a962"},{"url":"https://git.kernel.org/stable/c/a57d94026cb4fd7b3d258f0db2ad391cbccfaba5"},{"url":"https://git.kernel.org/stable/c/47d82b605351c0e04f6365e42c8ffe2fcfdba615"}],"title":"media: v4l2-async: avoid deleting unlinked ASC entry on link error","x_generator":{"engine":"bippy-1.2.0"}}}}
