{"id":"CVE-2026-74358","summary":"ext4: fix fast commit wait/wake bit mapping on 64-bit","details":"In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix fast commit wait/wake bit mapping on 64-bit\n\nOn 64-bit, ext4 dynamic inode states live in the upper half of i_flags,\nand ext4_test_inode_state() applies the corresponding +32 offset.\n\nThe fast-commit wait and wake paths open-coded the wait key with the raw\nEXT4_STATE_* value. Add small helpers for the state wait word and bit,\nand use them for the FC_COMMITTING and FC_FLUSHING_DATA waits so the wait\nkey follows the same mapping as the state helpers.","modified":"2026-08-18T03:31:16.700555063Z","published":"2026-08-15T05:58:42.789Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74358.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/8b3bc93fee6771775243665a0cf31857d6659775"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d06df6e447a8510f86db44b2522d5375362a9499"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e82d515092a0cf2bca92f399d5c330c324879cea"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74358.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74358"},{"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":"857d32f2618166765ce9306a246d0745afc76859"},{"fixed":"e82d515092a0cf2bca92f399d5c330c324879cea"},{"fixed":"d06df6e447a8510f86db44b2522d5375362a9499"},{"fixed":"8b3bc93fee6771775243665a0cf31857d6659775"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74358.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.16.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74358.json"}}],"schema_version":"1.9.0"}
