Arm Mali GPU Kernel Driver Use-After-Free Vulnerability
Known Exploited Vulnerabilities CVE-2021-29256 Mappings
. The Arm Mali GPU kernel driver allows an unprivileged user to achieve access to freed memory, leading to information disclosure or root privilege escalation. This affects Bifrost r16p0 through r29p0 before r30p0, Valhall r19p0 through r29p0 before r30p0, and Midgard r28p0 through r30p0.
This vulnerability is exploited by an unprivileged attacker by conducting malicious activity in GPU memory, gaining access to already freed memory. If successful, the threat actor could escalate their privileges to root as well as gain access to sensitive information. Detailed information about how adversaries exploit the GPU are not publicly available.
