5.5 · MEDIUM
Published Aug 21, 2024 linux CWE-476 EPSS 0.21% (11th pctl)

Overview

CVE-2022-48884 is a medium-severity vulnerability affecting linux linux_kernel. It was published on August 21, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: Fix command stats access after free

Command may fail while driver is reloading and can't accept FW commands

till command interface is reinitialized. Such command failure is being

logged to command stats. This results in NULL pointer access as command

stats structure is being freed and reallocated during mlx5 devlink

reload (see kernel log below).

Fix it by making command stats statically allocated on driver probe.
