Published: March 25, 2026
Vulnerability identifier: #VU124528
Vulnerability risk: Low
CVSSv4.0: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

Software vendor:
Linux Foundation
Linux Foundation
Description
The vulnerability allows a local user to execute arbitrary code and escalate privileges.
The vulnerability exists due to improper error handling in the vmw_translate_ptr functions in the drm/vmwgfx subsystem when translating pointers. A local user can trigger a use of an uninitialized pointer to cause out-of-bounds memory accesses and execute arbitrary code.
Successful exploitation may lead to privilege escalation and system compromise.
Remediation
Install security update from vendor's repository.
