caspy123/cve-2026-43499Linux kernel rtmutex vulnerability exploit with CVSS 7.8, providing proof-of-concept code for privilege escalation via improper waiter task handling in real-time mutex locks.
CVE-2026-43499 is a vulnerability within the Linux kernel, specifically affecting the rtmutex component, which is responsible for managing real-time mutex locks. This vulnerability arises from improper handling of waiter tasks during the queue operation of real-time locks, where the function remove_waiter() uses the current task instead of the intended waiter task.CVE-2026-43499 is a vulnerability within the Linux kernel, specifically affecting the rtmutex component, which is responsible for managing real-time mutex locks.
