This can likely be used\nto read arbitrary kernel memory, but can't corrupt kernel memory.\n\nFix it by calling locks_remove_posix() instead, which is designed to\nreliably get rid of POSIX locks associated with the given file and\nfiles_struct and is also used by filp_flush()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/locks.c"],"versions":[{"version":"c293621bbf678a3d85e3ed721c3921c8a670610d","lessThan":"d30ff33040834c3b9eee29740acd92f9c7ba2250","status":"affected","versionType":"git"},{"version":"c293621bbf678a3d85e3ed721c3921c8a670610d","lessThan":"dc2ce1dfceaa0767211a9d963ddb029ab21c4235","status":"affected","versionType":"git"},{"version":"c293621bbf678a3d85e3ed721c3921c8a670610d","lessThan":"5661b9c7ec189406c2dde00837aaa4672efb6240","status":"affected","versionType":"git"},{"version":"c293621bbf678a3d85e3ed721c3921c8a670610d","lessThan":"52c87ab18c76c14d7209646ccb3283b3f5d87b22","status":"affected","versionType":"git"},{"version":"c293621bbf678a3d85e3ed721c3921c8a670610d","lessThan":"ef8fc41cd6f95f9a4a3470f085aecf350569a0b3","status":"affected","versionType":"git"},{"version":"c293621bbf678a3d85e3ed721c3921c8a670610d","lessThan":"5f5d0799eb0a01d550c21b7894e26b2d9db55763","status":"affected","versionType":"git"},{"version":"c293621bbf678a3d85e3ed721c3921c8a670610d","lessThan":"b6d223942c34057fdfd8f149e763fa823731b224","status":"affected","versionType":"git"},{"version":"c293621bbf678a3d85e3ed721c3921c8a670610d","lessThan":"3cad1bc010416c6dd780643476bc59ed742436b9","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/locks.c"],"versions":[{"version":"2.6.13","status":"affected"},{"version":"0","lessThan":"2.6.13","status":"unaffected","versionType":"semver"},{"version":"4.19.319","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.281","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.223","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.164","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.101","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.42","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.9.9","lessThanOrEqual":"6.9.*","status":"unaffected","versionType":"semver"},{"version":"6.10","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":"2.6.13","versionEndExcluding":"4.19.319"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.13","versionEndExcluding":"5.4.281"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.13","versionEndExcluding":"5.10.223"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.13","versionEndExcluding":"5.15.164"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.13","versionEndExcluding":"6.1.101"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.13","versionEndExcluding":"6.6.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.13","versionEndExcluding":"6.9.9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.13","versionEndExcluding":"6.10"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/d30ff33040834c3b9eee29740acd92f9c7ba2250"},{"url":"https://git.kernel.org/stable/c/dc2ce1dfceaa0767211a9d963ddb029ab21c4235"},{"url":"https://git.kernel.org/stable/c/5661b9c7ec189406c2dde00837aaa4672efb6240"},{"url":"https://git.kernel.org/stable/c/52c87ab18c76c14d7209646ccb3283b3f5d87b22"},{"url":"https://git.kernel.org/stable/c/ef8fc41cd6f95f9a4a3470f085aecf350569a0b3"},{"url":"https://git.kernel.org/stable/c/5f5d0799eb0a01d550c21b7894e26b2d9db55763"},{"url":"https://git.kernel.org/stable/c/b6d223942c34057fdfd8f149e763fa823731b224"},{"url":"https://git.kernel.org/stable/c/3cad1bc010416c6dd780643476bc59ed742436b9"}],"title":"filelock:
