Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: drop gfx_v11_0_cp_ecc_error_irq_funcs The gfx.cp_ecc_error_irq is retired in gfx11. In gfx_v11_0_hw_fini still use amdgpu_irq_put to disable this interrupt, which caused the call trace in this function.

Impact Analysis

The impact of this vulnerability is that it can cause unexpected call traces or errors in the amdgpu driver on gfx11 hardware, potentially leading to instability or crashes related to GPU suspend, reset, or recovery operations.

Executive Summary

This vulnerability involves the Linux kernel's amdgpu driver where the gfx_v11_0_cp_ecc_error_irq_funcs, which is retired in gfx11 hardware, was still being used in the gfx_v11_0_hw_fini function to disable an interrupt. This caused a call trace (likely an error or crash) due to the use of a retired interrupt handler in the gfx11 version of the driver.

Detection Guidance

This vulnerability can be detected by checking the system logs for the specific call trace related to the gfx_v11_0_cp_ecc_error_irq_funcs issue in the amdgpu driver. You can use commands like 'dmesg | grep amdgpu' or 'journalctl -k | grep amdgpu' to look for the call trace entries shown in the description, such as 'gfx_v11_0_hw_fini', 'gfx_v11_0_suspend', and related amdgpu functions indicating the error.

Mitigation Strategies

Immediate mitigation involves updating the Linux kernel to a version where this vulnerability is resolved, as the fix involves dropping the gfx_v11_0_cp_ecc_error_irq_funcs and related code changes in the amdgpu driver. There are no other specific mitigation steps detailed in the provided information.
