{"id":"CVE-2026-53063","summary":"dm cache: fix write hang in passthrough mode","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndm cache: fix write hang in passthrough mode\n\nThe invalidate_remove() function has incomplete logic for handling write\nhit bios after cache invalidation. 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.","modified":"2026-07-08T08:09:45.512786108Z","published":"2026-06-24T16:30:06.857Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53063.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/05798d091ebcfb6d68228890e593f209e8ac940d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4ca8b8bd952df7c3ccdc68af9bd3419d0839a04b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/64d6519b00be4116d365bd31f33a5e5ce2944c1a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9fa18d0b981776b190ca4632942a7c2174052b78"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b8ace9e96983abb20ccf39edce8a60f1bb0b83d8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ecb10c193cbebf5e6984246a9b4ff1f95d45ed87"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53063.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53063"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"b29d4986d0da1a27cd35917cdb433672f5c95d7f"},{"fixed":"9fa18d0b981776b190ca4632942a7c2174052b78"},{"fixed":"ecb10c193cbebf5e6984246a9b4ff1f95d45ed87"},{"fixed":"64d6519b00be4116d365bd31f33a5e5ce2944c1a"},{"fixed":"b8ace9e96983abb20ccf39edce8a60f1bb0b83d8"},{"fixed":"05798d091ebcfb6d68228890e593f209e8ac940d"},{"fixed":"4ca8b8bd952df7c3ccdc68af9bd3419d0839a04b"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53063.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.12.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.141"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.91"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53063.json"}}],"schema_version":"1.7.5"}
