CVE-2024-46797

An improper locking flaw was found in the PowerPC architecture implementation of the Linux Kernel's queued spinlocks in the queued_spin_lock_slowpath() function. This issue occurs due to the interaction between CPU interrupts and the queued spinlock mechanism. When an interrupt occurs at a critical moment in the locking process, stale lock values can lead to erroneous operations, causing the system to hang. If a local attacker or an application puts the system under heavy load, a deadlock can occur when multiple CPUs are contending for locks, resulting in a denial of service condition.
