CVE-2025-39886: Undefined Security Weakness
In the Linux kernel, the following vulnerability has been resolved: bpf: Tell memcg to use allowspinning=false path in bpftimerinit Currently, calling bpfmapkmallocnode from bpfasyncinit can cause various locking issues; see the following stack trace edited for style as one example: ... 10.011566...
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-2025-21657
CVE-2025-21657 relates to the Linux kernel sched_ext component. The root cause was that scx_ops_bypass() re-enqueued scx tasks across CPUs by acquiring rq_lock() for online CPUs regardless of CPU state, which could trigger a spurious rq_pin_lock() warning. The fix replaces rq_lock() with raw_spin...
