Описание

A flaw was found in the Linux kernel. A missing buffer length check in the PKEY_VERIFYPROTK ioctl within the s390/pkey module allows a local attacker to provide a buffer length request that exceeds the allocated buffer size. This could lead to information disclosure by reading out-of-bounds memory or a denial of service by crashing the system.
