CVE-2023-28147

An issue was discovered in the Arm Mali GPU Kernel Driver. A non-privileged user can make improper GPU processing operat

An issue was discovered in the Arm Mali GPU Kernel Driver. A non-privileged user can make improper GPU processing operations to gain access to already freed memory. This affects Midgard r29p0 through r32p0, Bifrost r17p0 through r42p0 before r43p0, Valhall r19p0 through r42p0 before r43p0, and Arm's GPU Architecture Gen5 r41p0 through r42p0 before r43p0.
