Without taking a reference,\nthe trace_array may be freed via \"rmdir\" while a task is reading one of\ntheses files. Those files iterate all the events within an instance\n(trace_array) and nothing prevents that instance from being freed while\nits data is being read. This causes a use-after-free crash.\n\nHave the open of both those files take the trace_array reference via the\ntrace_array_get() that prevents the trace_array from being freed while the\nfiles are opened.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/2ee3f7d43f79efaca0cd84a6798653d9d75ce60b","https://git.kernel.org/stable/c/f4a771cc684c7354b6200147f7252c58d17408ff"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-90014","score":0.00165,"percentile":0.05674,"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).
