Summary

Imagination Technologies Graphics DDK versions 1.18 RTM2, 23.2 RTM2, 24.2 RTM2, 26.1 RTM2 and from 25.1 RTM2 through 25.3 RTM are affected. A 32-bit integer overflow in the kernel driver's page-to-byte conversion of an allocation size (CWE-190) results in an undersized kernel buffer. A local user running software without privileges can make improper system calls to exploit this and disclose sensitive kernel data.

Description from the CNA

Software installed and run as a non-privileged user may conduct improper system calls to allocate physical memory. A 32-bit integer overflow in the KM driver during page-to-byte conversion of an allocation size can result in an undersized kernel buffer allocation. This may allow unallocated or previously allocated physical pages to be mapped into an attacker-controlled GPU MMU context, leading to disclosure of sensitive kernel data.
