Vulnerability from github – Published: 2025-09-05 18:31 – Updated: 2025-11-25 21:32

Details

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

drm/nouveau/nvif: Fix potential memory leak in nvif_vmm_ctor().

When the nvif_vmm_type is invalid, we will return error directly without freeing the args in nvif_vmm_ctor(), which leading a memory leak. Fix it by setting the ret -EINVAL and goto done.

Severity ?
