{"id":"CVE-2026-90014","summary":"tracing: Have show_event_filters/triggers files take trace array ref","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ntracing: Have show_event_filters/triggers files take trace array ref\n\nThe newly added files show_event_filters and show_event_triggers that show\nall filters or triggers that are set within the trace array do not take a\nreference for the trace array it is showing. 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.","modified":"2026-09-18T03:48:34.665648096Z","published":"2026-09-16T10:33:20.791Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90014.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2ee3f7d43f79efaca0cd84a6798653d9d75ce60b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f4a771cc684c7354b6200147f7252c58d17408ff"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90014.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90014"},{"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":"729757b96a662d87e334fe8b837707800d8fd551"},{"fixed":"2ee3f7d43f79efaca0cd84a6798653d9d75ce60b"},{"fixed":"f4a771cc684c7354b6200147f7252c58d17408ff"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90014.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90014.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
