CVE-2021-47454

CVE-2021-47454 describes a Linux kernel vulnerability affecting powerpc SMP idle handling. The issue arises with PREEMPT_COUNT=y: when a CPU is offlined and onlined, the idle task’s preempt count could be decremented in CPU offline, triggering a scheduling panic. The root cause is that powerpc ar...
