CVE-2025-21657

In the Linux kernel, the following vulnerability has been resolved: schedext: Replace rqlock to rawspinrqlock in scxopsbypass scxopsbypass iterates all CPUs to re-enqueue all the scx tasks. For each CPU, it acquires a lock using rqlock regardless of whether a CPU is offline or the CPU is currentl...

CVE-2024-57891

The CVE refers to a Linux kernel issue fixed in the sched_ext subsystem: an invalid IRQ restore could occur due to improper conversion of an inner rq_unlock_irqrestore() to rq_unlock() when adding outer irqsave/restore locking in scx_ops_bypass(). This could lead to the IRQs being re-enabled at a...
