An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in
the f2fs module in the Linux kernel in versions before 5.12.0-rc4. A bounds
check failure allows a local attacker 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 system availability.
