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.","state":0,"publishedAt":"2026-09-16T10:33:20.791+00:00","modifiedAt":"2026-10-19T08:56:28.002+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"kernel/trace/trace_events.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"729757b96a662d87e334fe8b837707800d8fd551\",\n                            \"lessThan\": \"2ee3f7d43f79efaca0cd84a6798653d9d75ce60b\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"729757b96a662d87e334fe8b837707800d8fd551\",\n                            \"lessThan\": \"f4a771cc684c7354b6200147f7252c58d17408ff\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"kernel/trace/trace_events.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.0\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.5\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/2ee3f7d43f79efaca0cd84a6798653d9d75ce60b","https://git.kernel.org/stable/c/f4a771cc684c7354b6200147f7252c58d17408ff"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-90014","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-90014","identifiers":["CVE-2026-90014"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
