Descriptions

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.

El controlador del kernel de la GPU Arm Mali permite una escalada de privilegios o una denegación de servicio (corrupción de memoria) porque un usuario sin privilegios puede conseguir acceso de lectura/escritura a páginas de sólo lectura. Esto afecta a Bifrost r0p0 hasta r29p0 antes de r30p0, Valhall r19p0 hasta r29p0 antes de r30p0, y Midgard r8p0 hasta r30p0 antes de r31p0

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.
