CVE-2026-45976 Details
Description
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.
A memory leak vulnerability has been identified in the Linux kernel's AMDGPU driver. The issue arises in the 'amdgpu_ras_init' function, where the 'amdgpu_nbio_ras_sw_init' call can fail, causing the function to exit without freeing the allocated 'con' structure. This oversight leads to a memory leak. The vulnerability affects the Linux kernel stable tree.
The vulnerability has been addressed in the Linux kernel. Users can apply the latest patches available in the Linux kernel stable tree to mitigate this issue.
