CVE-2023-53074

Kernel warning via redundant firmware-buffer pinning

Published May 2, 2025 · Updated May 11, 2026

Resource-management flaw in Linux kernel 4.12 through 6.1.20 and 6.2 through 6.2.7 allows local users to trigger an AMDGPU teardown warning. The mode1 suspend-to-resume path unnecessarily reinitializes the trusted-application firmware buffer, incrementing its buffer-object pin count a second time. GPU removal then frees the mismatched buffer state and emits a call trace; reaching this path requires root privileges and an AMD GPU.
