Linux kernel smb2pdu.c file out-of-bounds read vulnerability

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. An out-of-bounds read vulnerability exists in versions of Linux kernel prior to 6.3.4, which stems from fs/ksmbd/smb2pdu.c not properly checking the UserName value, and can be exploited by an attacker to cause an out-of-bounds read.
