Linux Distros Unpatched Vulnerability : CVE-2022-49333

medium Nessus Plugin ID 225750

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - In the Linux kernel, the following vulnerability has been resolved: net/mlx5: E-Switch, pair only capable devices OFFLOADS paring using devcom is possible only on devices that support LAG. Filter based on lag capabilities. This fixes an issue where mlx5_get_next_phys_dev() was called without holding the interface lock. This issue was found when commit bc4c2f2e0179 (net/mlx5: Lag, filter non compatible devices) added an assert that verifies the interface lock is held.
