It then uses\nfind_next_zero_bit_le on the allocated region. find_next_zero_bit_le\naccesses the bitmap using unsigned long pointers. So, on 64-bit\narchitectures, it may access 4 bytes beyond the allocated size.\n\nFix this bug by rounding up bitset_size to BITS_PER_LONG.\n\nThis bug was found by running the lvm2 testsuite with kasan."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/md/dm-log.c"],"versions":[{"version":"29121bd0b00ebb9524971a583fea4a2f7afe8041","lessThan":"ae460312875159285cef5bf3dc654593f404a1ef","status":"affected","versionType":"git"},{"version":"29121bd0b00ebb9524971a583fea4a2f7afe8041","lessThan":"ba751f0d25f07aa21ce9b85372a3792bf7969d13","status":"affected","versionType":"git"},{"version":"29121bd0b00ebb9524971a583fea4a2f7afe8041","lessThan":"0d2209b54f1de0c2f99cab246d4cf2cfe24aaaa9","status":"affected","versionType":"git"},{"version":"29121bd0b00ebb9524971a583fea4a2f7afe8041","lessThan":"9a02f3275acc628c0d956be771405ced79ac36df","status":"affected","versionType":"git"},{"version":"29121bd0b00ebb9524971a583fea4a2f7afe8041","lessThan":"85e123c27d5cbc22cfdc01de1e2ca1d9003a02d0","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/md/dm-log.c"],"versions":[{"version":"2.6.18","status":"affected"},{"version":"0","lessThan":"2.6.18","status":"unaffected","versionType":"semver"},{"version":"5.4.200","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.124","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.49","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"5.18.6","lessThanOrEqual":"5.18.*","status":"unaffected","versionType":"semver"},{"version":"5.19","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":"2.6.18","versionEndExcluding":"5.4.200"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.18","versionEndExcluding":"5.10.124"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.18","versionEndExcluding":"5.15.49"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.18","versionEndExcluding":"5.18.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.18","versionEndExcluding":"5.19"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/ae460312875159285cef5bf3dc654593f404a1ef"},{"url":"https://git.kernel.org/stable/c/ba751f0d25f07aa21ce9b85372a3792bf7969d13"},{"url":"https://git.kernel.org/stable/c/0d2209b54f1de0c2f99cab246d4cf2cfe24aaaa9"},{"url":"https://git.kernel.org/stable/c/9a02f3275acc628c0d956be771405ced79ac36df"},{"url":"https://git.kernel.org/stable/c/85e123c27d5cbc22cfdc01de1e2ca1d9003a02d0"}],"title":"dm mirror log: round up region bitmap size to BITS_PER_LONG","x_generator":{"engine":"bippy-1.2.0"}}}}
