CVE-2024-56701

CVE-2024-56701: Linux kernel powerpc/pseries code fixed a sleeping-lock issue by changing dtl_access_lock to a rw_semaphore because kmalloc() can sleep while held. Root cause: a non-sleeping lock protected code path that sleeps, causing a potential sleep in atomic context. Impact is local (LOCAL)...
