The cifsFileInfo reference and the open\nserver handle both leak.\n\nFix by saving the cfile that failed allocation in a local variable,\nbreaking as before, and calling _cifsFileInfo_put() on it after\nreleasing the lock.  Any files later in the iteration are unaffected\nsince their deferred work is still pending and will fire normally."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/smb/client/misc.c"],"versions":[{"version":"e3fc065682ebbbd15b0ce0036800f4acbf765d46","lessThan":"32390b3f06f26e366cfb27dbac4bc0196c321535","status":"affected","versionType":"git"},{"version":"e3fc065682ebbbd15b0ce0036800f4acbf765d46","lessThan":"c2f2e83e3bbc5483730fd4ee903182761f1ae50f","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/smb/client/misc.c"],"versions":[{"version":"5.15","status":"affected"},{"version":"0","lessThan":"5.15","status":"unaffected","versionType":"semver"},{"version":"7.1.6","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"5.15","versionEndExcluding":"7.1.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/32390b3f06f26e366cfb27dbac4bc0196c321535"},{"url":"https://git.kernel.org/stable/c/c2f2e83e3bbc5483730fd4ee903182761f1ae50f"}],"title":"cifs: fix cifsFileInfo leak on kmalloc failure in deferred close drain paths","x_generator":{"engine":"bippy-1.2.0"}}}}
