CVE-2025-71080

CVE-2025-71080 involves a race in the Linux kernel on PREEMPT_RT where rt6_get_pcpu_route() may return NULL and allow another task on the same CPU to install a pcpu_rt entry, causing a later cmpxchg() failure and a BUG_ON(prev). The fix makes the cmpxchg() failure graceful by freeing the allocati...
