{"id":"CVE-2026-98445","summary":"xfs: don't let memory failures leak blocks and kill repairs","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: don't let memory failures leak blocks and kill repairs\n\nLOLLM complains that a memory allocation failure in\nxrep_newbt_add_blocks results in online repair leaking blocks that were\npreviously allocated to write a new btree, but the problem is worse than\nthat -- a limitation of the codebase is that the callers cannot undo the\ntransaction /and/ return the error -- either you undo all changes and\ncommit the transaction, or you error out and the filesystem goes down.\n\nHowever, the new btree space reservation object isn't that big (~48\nbytes).  Let's just do a NOFAIL allocation and the problem goes away.","modified":"2026-10-20T02:30:38.624556571Z","published":"2026-10-18T15:14:55.754Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98445.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0e0d3372a84029da1768c7a4c4601484af5b58a2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3380151cf0ce8ad0c1d356fed51e4b69e1d28e50"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ab1c416d2377cdc16123ef521aac4da1c468c3d4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b15c79fca28060fd9c7e77f2c3ebc4ba023974e8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98445.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98445"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"be408417630427984a1fddd069f30b245793234c"},{"fixed":"3380151cf0ce8ad0c1d356fed51e4b69e1d28e50"},{"fixed":"b15c79fca28060fd9c7e77f2c3ebc4ba023974e8"},{"fixed":"0e0d3372a84029da1768c7a4c4601484af5b58a2"},{"fixed":"ab1c416d2377cdc16123ef521aac4da1c468c3d4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98445.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.8.0"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.56"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98445.json"}}],"schema_version":"1.9.0"}
