The existing checks on fp->refcount are not sufficient to\nprevent this.\n\nThe fix takes ft->lock around the section which removes the\nfile from the file table. This prevents two threads acquiring the\nsame file pointer via __close_file_table_ids, as well as the other\nfunctions which retrieve a file from the IDR and which already use\nthis same lock."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/smb/server/vfs_cache.c"],"versions":[{"version":"0626e6641f6b467447c81dd7678a69c66f7746cf","lessThan":"fec1f9e9a650e8e7011330a085c77e7bf2a08ea9","status":"affected","versionType":"git"},{"version":"0626e6641f6b467447c81dd7678a69c66f7746cf","lessThan":"9e9841e232b51171ddf3bc4ee517d5d28dc8cad6","status":"affected","versionType":"git"},{"version":"0626e6641f6b467447c81dd7678a69c66f7746cf","lessThan":"16727e442568a46d9cca69fe2595896de86e120d","status":"affected","versionType":"git"},{"version":"0626e6641f6b467447c81dd7678a69c66f7746cf","lessThan":"36991c1ccde2d5a521577c448ffe07fcccfe104d","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/server/vfs_cache.c"],"versions":[{"version":"5.15","status":"affected"},{"version":"0","lessThan":"5.15","status":"unaffected","versionType":"semver"},{"version":"6.6.91","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.29","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.14.7","lessThanOrEqual":"6.14.*","status":"unaffected","versionType":"semver"},{"version":"6.15","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":"6.6.91"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15","versionEndExcluding":"6.12.29"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15","versionEndExcluding":"6.14.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15","versionEndExcluding":"6.15"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/fec1f9e9a650e8e7011330a085c77e7bf2a08ea9"},{"url":"https://git.kernel.org/stable/c/9e9841e232b51171ddf3bc4ee517d5d28dc8cad6"},{"url":"https://git.kernel.org/stable/c/16727e442568a46d9cca69fe2595896de86e120d"},{"url":"https://git.kernel.org/stable/c/36991c1ccde2d5a521577c448ffe07fcccfe104d"}],"title":"ksmbd: Fix UAF in __close_file_table_ids","x_generator":{"engine":"bippy-1.2.0"}}}}
