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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/4096fd0e8eaea13ebe5206700b33f49635ae18e5","https://git.kernel.org/stable/c/9401b593fa48218d2667df1610b0ebc518554880"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-31574","score":0.00107,"percentile":0.01153,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
