AI-suggested

A patch is available and should be applied to affected Linux kernel versions. The vendor advisory (Ubuntu Security Notice USN-8029-1) confirms that this issue is fixed in updated kernel releases. Users should update their Linux kernel to versions including this fix to prevent system hangs caused by this vulnerability.

Description

A vulnerability in the Linux kernel's clock framework for the thead th1520-ap platform was resolved. The AXI crossbar of TH1520 lacks proper timeout handling, causing gating of AXI clocks to potentially lead to bus timeouts and system hangs. The fix sets all AXI clock gates to CLK_IS_CRITICAL to prevent unwanted clock gating. This issue was addressed as part of a broader Linux kernel security update.
