Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel (Operating System) (the affected version is unknown). Affected is an unknown code of the file drivers/gpu/drm/vmwgfx/vmwgfx_bo.c of the component vmwgfx Driver. The manipulation with an unknown input leads to a double free vulnerability. CWE is classifying the issue as CWE-415. The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A double-free vulnerability was found in handling vmw_buffer_object objects in the vmwgfx driver in the Linux kernel. This issue occurs due to the lack of validating the existence of an object prior to performing further free operations on the object, which may allow a local privileged user to escalate privileges and execute code in the context of the kernel.

The weakness was shared 05/27/2023. The advisory is available at zerodayinitiative.com. This vulnerability is traded as CVE-2023-33952 since 05/24/2023. Technical details are known, but there is no available exploit.
