It sets up the remapping for the\noverwrite_bio but then drops it immediately without submission, causing\nwrite operations to hang.\n\nFix by adding a new invalidate_committed() continuation that submits\nthe remapped writes to the cache origin after metadata commit completes,\nwhile using the overwrite_endio hook to ensure proper completion\nsequencing. This maintains existing coherency. Also improve error\nhandling in invalidate_complete() to preserve the original error status\ninstead of using bio_io_error() unconditionally."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/md/dm-cache-target.c"],"versions":[{"version":"b29d4986d0da1a27cd35917cdb433672f5c95d7f","lessThan":"9fa18d0b981776b190ca4632942a7c2174052b78","status":"affected","versionType":"git"},{"version":"b29d4986d0da1a27cd35917cdb433672f5c95d7f","lessThan":"ecb10c193cbebf5e6984246a9b4ff1f95d45ed87","status":"affected","versionType":"git"},{"version":"b29d4986d0da1a27cd35917cdb433672f5c95d7f","lessThan":"64d6519b00be4116d365bd31f33a5e5ce2944c1a","status":"affected","versionType":"git"},{"version":"b29d4986d0da1a27cd35917cdb433672f5c95d7f","lessThan":"b8ace9e96983abb20ccf39edce8a60f1bb0b83d8","status":"affected","versionType":"git"},{"version":"b29d4986d0da1a27cd35917cdb433672f5c95d7f","lessThan":"05798d091ebcfb6d68228890e593f209e8ac940d","status":"affected","versionType":"git"},{"version":"b29d4986d0da1a27cd35917cdb433672f5c95d7f","lessThan":"4ca8b8bd952df7c3ccdc68af9bd3419d0839a04b","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-cache-target.c"],"versions":[{"version":"4.12","status":"affected"},{"version":"0","lessThan":"4.12","status":"unaffected","versionType":"semver"},{"version":"6.1.175","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.141","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.91","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.33","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.10","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","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":"4.12","versionEndExcluding":"6.1.175"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.6.141"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.12.91"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.18.33"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"7.0.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/9fa18d0b981776b190ca4632942a7c2174052b78"},{"url":"https://git.kernel.org/stable/c/ecb10c193cbebf5e6984246a9b4ff1f95d45ed87"},{"url":"https://git.kernel.org/stable/c/64d6519b00be4116d365bd31f33a5e5ce2944c1a"},{"url":"https://git.kernel.org/stable/c/b8ace9e96983abb20ccf39edce8a60f1bb0b83d8"},{"url":"https://git.kernel.org/stable/c/05798d091ebcfb6d68228890e593f209e8ac940d"},{"url":"https://git.kernel.org/stable/c/4ca8b8bd952df7c3ccdc68af9bd3419d0839a04b"}],"title":"dm cache: fix write hang in passthrough mode","x_generator":{"engine":"bippy-1.2.0"}}}}
