If the subsequent\nposix_cpu_timer_set() call fails, the function returns immediately\nwithout calling posix_cpu_timer_del() to release the pid reference,\ncausing a leak.\n\nFix it by calling posix_cpu_timer_del() before the unlock-and-return\non the error path, consistent with the other exit paths in the same\nfunction.","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/7776f9226e99eb49d97492b0b445027cfcb189da","https://git.kernel.org/stable/c/87bd2ad568e15b90d5f7d4bcd70342d05dad649c","https://git.kernel.org/stable/c/8a270b1258797f61b61da44f8bfd41a581b5c85b","https://git.kernel.org/stable/c/8f06363446c5d043c9a7c008b250040e9de98cf9","https://git.kernel.org/stable/c/afed3cdc1cca133f804fcf57ff228974f424b23a"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:46:40.600842820+00:00"},"epss":{"cve":"CVE-2026-64370","score":0.00129,"percentile":0.02493,"date":"2026-10-25"},"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).
