{"id":"CVE-2026-45899","summary":"ext4: drop extent cache when splitting extent fails","details":"In the Linux kernel, the following vulnerability has been resolved:\n\next4: drop extent cache when splitting extent fails\n\nWhen the split extent fails, we might leave some extents still being\nprocessed and return an error directly, which will result in stale\nextent entries remaining in the extent status tree. So drop all of the\nremaining potentially stale extents if the splitting fails.","modified":"2026-07-08T08:13:34.847431585Z","published":"2026-05-27T12:17:08.447Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45899.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/120c6bd7ca9d3e80a968b758cbb3fbd67570f132"},{"type":"WEB","url":"https://git.kernel.org/stable/c/31bf37cf53ede8145e2bc62da803d4506da92975"},{"type":"WEB","url":"https://git.kernel.org/stable/c/337506dc652383c80839edb8d8dcdd8ff2129b4f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6e54f8dfee359bbd58086c883ea8cffd5312999d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/79b592e8f1b435796cbc2722190368e3e8ffd7a1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/808f3191498f300174523c54cab101e18795ae4e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dc7c9b9d03a59a7fe483574531327e650a4b4adc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45899.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45899"},{"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":"107a7bd31ac003e42c0f966aa8e5b26947de6024"},{"fixed":"6e54f8dfee359bbd58086c883ea8cffd5312999d"},{"fixed":"337506dc652383c80839edb8d8dcdd8ff2129b4f"},{"fixed":"dc7c9b9d03a59a7fe483574531327e650a4b4adc"},{"fixed":"120c6bd7ca9d3e80a968b758cbb3fbd67570f132"},{"fixed":"808f3191498f300174523c54cab101e18795ae4e"},{"fixed":"31bf37cf53ede8145e2bc62da803d4506da92975"},{"fixed":"79b592e8f1b435796cbc2722190368e3e8ffd7a1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45899.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.12.0"},{"fixed":"5.10.253"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.203"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.6.130"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.14"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45899.json"}}],"schema_version":"1.7.5"}
