The util_format_is_pure_uint function in vrend_renderer.c in Virgil 3d project (aka virglrenderer) 0.6.0 and earlier allows local guest OS users to cause a denial of service (NULL pointer dereference) via a crafted VIRGL_CCMD_CLEAR command.
AnalysisAI
The util_format_is_pure_uint function in vrend_renderer.c in Virgil 3d project (aka virglrenderer) 0.6.0 and earlier allows local guest OS users to cause a denial of service (NULL pointer. Rated medium severity (CVSS 6.5), this vulnerability is low attack complexity. This NULL Pointer Dereference vulnerability could allow attackers to crash the application by dereferencing a null pointer.
Technical ContextAI
This vulnerability is classified as NULL Pointer Dereference (CWE-476), which allows attackers to crash the application by dereferencing a null pointer. The util_format_is_pure_uint function in vrend_renderer.c in Virgil 3d project (aka virglrenderer) 0.6.0 and earlier allows local guest OS users to cause a denial of service (NULL pointer dereference) via a crafted VIRGL_CCMD_CLEAR command. Affected products include: Virglrenderer Project Virglrenderer.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Check pointers before dereferencing. Use static analysis tools to detect null pointer paths.
