Use-After-Free in Arm Bifrost and Valhall GPU Kernel Drivers
CVE-2024-4610 is a use-after-free vulnerability in Arm Ltd.'s Bifrost and Valhall GPU kernel drivers. According to the provided content, a local non-privileged user can trigger improper GPU memory processing operations and gain access to memory that has already been freed. The issue affects Bifrost GPU Kernel Driver and Valhall GPU Kernel Driver versions r34p0 through r40p0. The flaw is in kernel-mode GPU driver memory handling, where freed memory can still be referenced or accessed after release, creating a condition that can be abused from a local context.
