CVE-2026-45976

Estado: AnalizadaMedia (5.5)—

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

drm/amdgpu: Fix memory leak in amdgpu_ras_init()

When amdgpu_nbio_ras_sw_init() fails in amdgpu_ras_init(), the function returns directly without freeing the allocated con structure, leading to a memory leak.

Fix this by jumping to the release_con label to properly clean up the allocated memory before returning the error code.

Compile tested only. Issue found using a prototype static analysis tool and code review.
