Kerentanan Out-of-bounds Write pada linux kernel, canonical ubuntu linux. Skor CVSS 3.1 6.0 (Medium) menurut NVD.

Deskripsi (NVD)

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 “is 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.”
