The latter cannot make progress due to state\nrecovery being needed.\n\nIt seems that the only safe thing to do here is to kick off a writeback\nof the folio, without waiting for completion, or else kicking off an\nasynchronous commit.","modified":"2026-04-02T17:29:41.012063474Z","published":"2026-02-04T16:04:22.574Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:20667-1","SUSE-SU-2026:20720-1","SUSE-SU-2026:20838-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23053.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/19b4d9ab5e77843eac0429c019470c02f8710b55"},{"type":"WEB","url":"https://git.kernel.org/stable/c/49d352bc263fe4a834233338bfaad31b3109addf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a4810f8beb0122f032f10735f98d257aa6064f4c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cce0be6eb4971456b703aaeafd571650d314bcca"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23053.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23053"},{"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":"96780ca55e3cbf4f150fd5a833a61492c9947b5b"},{"fixed":"a4810f8beb0122f032f10735f98d257aa6064f4c"},{"fixed":"49d352bc263fe4a834233338bfaad31b3109addf"},{"fixed":"19b4d9ab5e77843eac0429c019470c02f8710b55"},{"fixed":"cce0be6eb4971456b703aaeafd571650d314bcca"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23053.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.3.0"},{"fixed":"6.6.130"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.67"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23053.json"}}],"schema_version":"1.7.5"}
