Description
A flaw was found in the drm/amdgpu component of the Linux kernel. The amdgpu_acpi_vfct_bios() function fails to release a reference to the VFCT ACPI table after fetching it. This oversight leads to a resource leak, where memory allocated for the table mapping is not properly freed, potentially impacting system stability over time.
Statement
This issue affects AMDGPU systems using VFCT ACPI tables for VBIOS. amdgpu_acpi_vfct_bios() fetches the ACPI table but never releases it, leaking references on each call. Systems without AMD GPUs are not affected.
