An out-of-bounds (OOB) memory access flaw was found in x25_bind in
net/x25/af_x25.c in the Linux kernel version v5.12-rc5. A bounds check
failure allows a local attacker with a user account on the system to gain
access to out-of-bounds memory, leading to a system crash or a leak of
internal kernel information. The highest threat from this vulnerability is
to confidentiality, integrity, as well as system availability.
