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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":205015,"id":"CVE-2026-90014","ts":1789570703648,"field":"cvss","old":null,"new":"7.8"},{"seq":205014,"id":"CVE-2026-90014","ts":1789570703648,"field":"severity","old":"none","new":"high"}]}
