This means fuse_chan_abort() can end the\nrequest and free the fuse_io_args (eg fuse_readpages_end()) while the\nsubsequent copy chain logic after fuse_try_move_folio() accesses the\nfuse_io_args, leading to use-after-free issues.\n\nFix this by calling lock_request() before replace_page_cache_folio().\nThis ensures the request is locked on the success path which will\nprevent the fuse_io_args from being freed while the later copying logic\nruns, and also ensures that the ap->folios[i]->mapping is never null\nsince ap->folios[i] will always point to the newfolio after\nreplace_page_cache_folio()."}], "lastModified": "2026-07-29T19:30:41.847", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "EBBA269B-EFFD-4A82-9798-148031D55E9A", "versionEndExcluding": "5.15.211", "versionStartIncluding": "2.6.35"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "333C9E30-7FD4-46A2-94EF-C1AA1F3EE28B", "versionEndExcluding": "6.1.177", "versionStartIncluding": "5.16"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C8AD3BC8-C843-423C-B9DB-CB52F67F578E", "versionEndExcluding": "6.6.144", "versionStartIncluding": "6.2"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4E206B86-E0E3-4394-A93F-39F2D50A8AA8", "versionEndExcluding": "6.12.95", "versionStartIncluding": "6.7"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E08ACB05-518A-4D61-A6C4-268D1BB6BF46", "versionEndExcluding": "6.18.37", "versionStartIncluding": "6.13"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "6241DF06-E6F3-4B61-B5A2-A60F2AE5B982", "versionEndExcluding": "7.0.14", "versionStartIncluding": "6.19"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C18FAA06-B61A-4036-A12D-F06F5135E64B", "versionEndExcluding": "7.1.2", "versionStartIncluding": "7.1"}], "operator": "OR"}]}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
