Overview

CVE-2023-53471 is a high-severity vulnerability. It was published on October 1, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu/gfx: disable gfx9 cp_ecc_error_irq only when enabling legacy gfx ras

gfx9 cp_ecc_error_irq is only enabled when legacy gfx ras is assert.

So in gfx_v9_0_hw_fini, interrupt disablement for cp_ecc_error_irq

should be executed under such condition, otherwise, an amdgpu_irq_put

calltrace will occur.
