Summary
Vulnerability in linux-hwe-edge (UBUNTU-CVE-2025-22032). Risk of unauthorized operations or information disclosure. Exploitable via mt792x_rx_get_wcid. Mitigation: upgrade to 6.11.0-1018.18~24.04.1 or later.
Original description
The description as published by the source.
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: fix kernel panic due to null pointer dereference Address a kernel panic caused by a null pointer dereference in the mt792x_rx_get_wcid function. The issue arises because the deflink structure is not properly initialized with the sta context. This patch ensures that the deflink structure is correctly linked to the sta context, preventing the null pointer dereference.
