CVE-2021-28664: Arm Mali Graphics Processing Unit (GPU) Unspecified Vulnerability
Arm Mali Graphics Processing Unit (GPU) kernel driver contains an unspecified vulnerability that may allow a non-privileged user to gain write access to read-only memory, gain root privilege, corrupt memory, and modify the memory of other processes.
Other sources
The Arm Mali GPU kernel driver allows privilege escalation or a denial of service (memory corruption) because an unprivileged user can achieve read/write access to read-only pages. This affects Bifrost r0p0 through r29p0 before r30p0, Valhall r19p0 through r29p0 before r30p0, and Midgard r8p0 through r30p0 before r31p0.
