Description

An issue was discovered in net/ceph/messenger_v2.c in the Linux kernel before 6.4.5. There is an integer signedness error, leading to a buffer overflow and remote code execution via HELLO or one of the AUTH frames. This occurs because of an untrusted length taken from a TCP packet in ceph_decode_32.
