CVE-2025-21767

CVE-2025-21767 is a Linux kernel issue where clocksource_verify_choose_cpus() is invoked with preemption disabled, causing a call to get_random_u32() that can indirectly acquire sleeping locks in PREEMPT_RT contexts. The root cause is using get_random_u32() while preemption is off, leading to an ...
