{"apiVersion":"1.0","identifier":"CVE-2026-99237","description":"In the Linux kernel, the following vulnerability has been resolved: tracing: Hold trace_types_lock when resetting last boot data from readers update_last_data_if_empty() is called from tracing_open() with O_TRUNC, tracing_read_pipe() and tracing_buffers_read() without trace_types_lock. Two readers can both pass the LAST_BOOT test and free module_delta twice, and a module notifier can update module_delta while it is being freed. Take trace_types_lock in those paths and keep the callers that already hold it on an unlocked variant.","publishedAt":"2026-11-02T16:17:49","lastModifiedAt":"2026-11-03T20:18:30","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-99237","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.0012,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-99237","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-99237","en":"https://www.redsauce.net/en/cves/CVE-2026-99237","fr":"https://www.redsauce.net/fr/cves/CVE-2026-99237","pt":"https://www.redsauce.net/pt/cves/CVE-2026-99237","de":"https://www.redsauce.net/de/cves/CVE-2026-99237","sk":"https://www.redsauce.net/sk/cves/CVE-2026-99237","el":"https://www.redsauce.net/el/cves/CVE-2026-99237"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-99237"}}
