[SRU][Bionic][PATCH 0/1] Fix for CVE-2021-3506

[Joseph Salisbury]

[Impact]
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.

[Fix]
b862676e3717 ("f2fs: fix to avoid out-of-bounds memory access")

[Potential regression]
This change is limited to f2fs.
