Vulnerability in linux-hwe-edge (UBUNTU-CVE-2024-45019)

Summary

Vulnerability in linux-hwe-edge (UBUNTU-CVE-2024-45019). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 6.8.0-1020.22~22.04.1 or later.

Original description

The description as published by the source.

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Take state lock during tx timeout reporter mlx5e_safe_reopen_channels() requires the state lock taken. The referenced changed in the Fixes tag removed the lock to fix another issue. This patch adds it back but at a later point (when calling mlx5e_safe_reopen_channels()) to avoid the deadlock referenced in the Fixes tag.
