Technical details
A Time-of-Check Time-of-Use (TOCTOU) race condition exists in the Imagination Technologies Graphics DDK. Kernel software running within a guest VM can post commands to the GPU firmware; a malicious driver can modify command values in memory after the firmware has validated them but before they are executed. This allows the attacker to trigger memory writes outside the permitted range of the host kernel. The vulnerability affects multiple versions of the Graphics DDK on Linux and Android platforms and is addressed in version 26.1 RTM2.
Affected products
- Imagination Technologies Graphics DDK 1.18 RTM2, 23.2 RTM2, 24.2 RTM2, 25.1 RTM2 to 25.3 RTM, 26.1 RTM1
