Vulnerability Name:

CVE-2021-28664 (CCN-201528)

Assigned:2021-03-18
Published:2021-03-18
Updated:2022-10-27
Summary: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.
