{"id":"CVE-2026-31574","summary":"clockevents: Add missing resets of the next_event_forced flag","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nclockevents: Add missing resets of the next_event_forced flag\n\nThe prevention mechanism against timer interrupt starvation missed to reset\nthe next_event_forced flag in a couple of places:\n\n    - When the clock event state changes. That can cause the flag to be\n      stale over a shutdown/startup sequence\n\n    - When a non-forced event is armed, which then prevents rearming before\n      that event. If that event is far out in the future this will cause\n      missed timer interrupts.\n\n    - In the suspend wakeup handler.\n\nThat led to stalls which have been reported by several people.\n\nAdd the missing resets, which fixes the problems for the reporters.","modified":"2026-06-18T03:57:35.474443874Z","published":"2026-04-24T14:42:06.707Z","related":["CGA-3jg4-fcjw-v95c","openSUSE-SU-2026:10703-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31574.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4096fd0e8eaea13ebe5206700b33f49635ae18e5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9401b593fa48218d2667df1610b0ebc518554880"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31574.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31574"},{"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":"d6e152d905bdb1f32f9d99775e2f453350399a6a"},{"fixed":"9401b593fa48218d2667df1610b0ebc518554880"},{"fixed":"4096fd0e8eaea13ebe5206700b33f49635ae18e5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-31574.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.1"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-31574.json"}}],"schema_version":"1.7.5"}
