Description
This security bulletin contains information about 1 security vulnerability.
1) NULL Pointer Dereference (CVE-ID: CVE-2026-23317)
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
