CVE-2025-39679 Details
Description
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.
A memory leak vulnerability has been identified in the Linux kernel's Nouveau driver, specifically within the VMM (Virtual Memory Manager) constructor function. This issue arises when an invalid VMM type is encountered; the function returns an error without properly freeing allocated resources, leading to a memory leak. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for upgrading the Linux kernel can be found in the official Linux documentation.
