In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/gfx6: fix firmware leak on teardown The firmware requested in… (CVE-2026-98784)
Description
A vulnerability in the Linux kernel's AMDGPU driver (gfx6) caused firmware resources to leak during teardown. The issue was that firmware requested in gfx_v6_0_init_microcode() was not properly released when the GFX block was torn down. This was fixed by adding a function to free the microcode firmware and calling it during software finalization.

Technical Analysis
The Linux kernel AMDGPU gfx6 driver had a resource leak vulnerability where firmware loaded by gfx_v6_0_init_microcode() was not released on teardown of the GFX block. This caused firmware resources (PFP, ME, CE, and RLC firmware) to remain allocated unnecessarily. The fix involved adding gfx_v6_0_free_microcode() and invoking it from gfx_v6_0_sw_fini() to properly release these firmware resources, closing the leak.
Potential Impact
The vulnerability results in a firmware resource leak within the AMDGPU gfx6 driver in the Linux kernel. This could lead to inefficient resource utilization and potential stability or performance degradation over time. There is no indication of direct security compromise or exploitation in the wild.
Mitigation Recommendations
A fix has been implemented in the Linux kernel source code by adding a function to free the firmware microcode and calling it during teardown. Users should update to a Linux kernel version that includes this fix. Since this is a resource leak, no other specific mitigations are indicated.
