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 ...

kernel: arm64/sve: Discard stale CPU state when handling SVE traps
A flaw was found in the Linux kernel. A race condition in the 64-bit ARM arm64 architecture's handling of Scalable Vector Extension SVE traps can allow stale processor register states to be reused. A local user can trigger this flaw through specific task preemption timing to access sensitive data...
