priority inheritance

Priority inheritance is a mechanism in real-time scheduling that prevents priority inversion by temporarily raising a lower-priority task's priority when it holds a resource needed by a higher-priority task. On WindowsForum.com, discussions about priority inheritance often focus on Linux kernel bugs, such as CVE-2026-23371, which involves a missing ENQUEUE_REPLENISH flag during SCHED_DEADLINE priority inheritance de-boosting. This flaw can corrupt bandwidth accounting and trigger kernel warnings like running_bw underflow. The tag covers scheduler vulnerabilities, deadline scheduling, and the fragility of priority inheritance in real-time systems, particularly when tasks are demoted while holding mutexes.
