CVE-2026-7639
Last modified
CVE-2026-7639 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. Software installed and run as a non-privileged user may conduct a sequence of improper GPU system calls causing use after free, which helps in facilitating unprivileged memory access from a shader code. Triggering failure path in the MMU mapping logic by a malicious code could lead to incomplete cleanup of an internal driver state, allowing for future unauthorized access to the contents of the physical memory.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
