CVE-2017-6355: Freedesktop Virglrenderer

Medium severity, CVSS 5.5. EPSS: 0.4% chance of exploitation in the next 30 days.

Integer overflow in the vrend_create_shader function in vrend_renderer.c in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (process crash) via crafted pkt_length and offlen values, which trigger an out-of-bounds access.

Affected products
