{"id":"CVE-2026-53049","summary":"gfs2: add some missing log locking","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ngfs2: add some missing log locking\n\nFunction gfs2_logd() calls the log flushing functions gfs2_ail1_start(),\ngfs2_ail1_wait(), and gfs2_ail1_empty() without holding sdp-\u003esd_log_flush_lock,\nbut these functions require exclusion against concurrent transactions.\n\nTo fix that, add a non-locking __gfs2_log_flush() function.  Then, in\ngfs2_logd(), take sdp-\u003esd_log_flush_lock before calling the above mentioned log\nflushing functions and __gfs2_log_flush().","modified":"2026-07-08T08:09:45.285830846Z","published":"2026-06-24T16:29:55.190Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53049.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3b28eb75afe520972bacc833850c2b30aa0824cd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/49d9be0722da3a4a893ba905720cba1921834ec3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/98e8bf249c790d56de1abc4a5f8bd68035a00921"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bf5fcd9c37c2546beaf7b401d31aefd89017dc3d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ca95342cb1b39062a03c115830286f0a426053d5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f2f225cf505ac016132ded21690f3ba0a080a4e8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fe2c8d051150b90b3ccb85f89e3b1d636cb88ec8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53049.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53049"},{"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":"5e4c7632aae1cce137792647f4fb6f599d1da893"},{"fixed":"3b28eb75afe520972bacc833850c2b30aa0824cd"},{"fixed":"ca95342cb1b39062a03c115830286f0a426053d5"},{"fixed":"bf5fcd9c37c2546beaf7b401d31aefd89017dc3d"},{"fixed":"f2f225cf505ac016132ded21690f3ba0a080a4e8"},{"fixed":"49d9be0722da3a4a893ba905720cba1921834ec3"},{"fixed":"98e8bf249c790d56de1abc4a5f8bd68035a00921"},{"fixed":"fe2c8d051150b90b3ccb85f89e3b1d636cb88ec8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53049.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.7.0"},{"fixed":"5.15.209"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.141"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.91"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53049.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
