For cross-directory renames where the target parent\nis a descendant of the source parent, lock the target parent before the\nsource parent so the directory order matches the child-to-parent order used\nby ntfs_file_fsync(), ntfs_dir_fsync(), and __ntfs_write_inode()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/ntfs/namei.c"],"versions":[{"version":"af0db57d4293cc9fe6ce99fb5592dc2652228c9d","lessThan":"b3d09502b80dfe0bab9090ca532710da389f6c7f","status":"affected","versionType":"git"},{"version":"af0db57d4293cc9fe6ce99fb5592dc2652228c9d","lessThan":"eb94f5a41a193a425e09a63cb75dffd151d8f42e","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/ntfs/namei.c"],"versions":[{"version":"7.1","status":"affected"},{"version":"0","lessThan":"7.1","status":"unaffected","versionType":"semver"},{"version":"7.1.5","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":"7.1","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"7.1","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/b3d09502b80dfe0bab9090ca532710da389f6c7f"},{"url":"https://git.kernel.org/stable/c/eb94f5a41a193a425e09a63cb75dffd151d8f42e"}],"title":"ntfs: fix mrec_lock ABBA deadlock in rename","x_generator":{"engine":"bippy-1.2.0"}}}}
