CVE-2021-44828 (CCN-217480)

Assigned:2021-12-11
Published:2021-12-11
Updated:2022-01-21
Summary:Arm Mali GPU Kernel Driver (Midgard r26p0 through r30p0, Bifrost r0p0 through r34p0, and Valhall r19p0 through r34p0) allows a non-privileged user to achieve write access to read-only memory, and possibly obtain root privileges, corrupt memory, and modify the memory of other processes.
