EUVD-2026-43037

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...

CVE-2026-53312

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit component for RISC-V architectures. An integer overflow in the invalidation path can lead to an infinite loop. This vulnerability could allow a local attacker to cause a Denial of Service DoS by triggering the overfl...
