DISPUTED An issue was discovered in the Linux kernel through 5.6.2.
mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write
because an empty nodelist is mishandled during mount option parsing, aka
CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that
this is a vulnerability because the issue βis a bug in parsing mount
options which can only be specified by a privileged user, so triggering the
bug does not grant any powers not already held.β.
