Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a read and/or write data outside the Guest's virtualised GPU memory. The firmware uses data provided by the Guest VM to set up accesses to memory. It validated this before use, but a TOCTOU bug was present which allowed the earlier check results to be invalidated.
Software installed and run as a non-privileged user may conduct improper GPU driver IOCTL calls to create an allocation scenario that when freed would cause double free and kernel heap corruption. Scenario caused by fabricating a specific combination of flags on the allocation interface that would cause an incorrect double free event when freed.
Privilege escalation in Imagination Technologies Graphics DDK allows guest VM kernel software to issue crafted commands to GPU Firmware, triggering writes outside the guest's virtualized GPU memory boundary (CWE-823). Affected are multiple DDK release trains including versions 25.1 RTM2 through 25.3 RTM, 24.2 RTM2, 23.2 RTM2, and 1.18 RTM2. No public exploit code exists and CISA has not added this to KEV; however, SSVC assesses total technical impact given successful exploitation yields full C/I/A compromise of the guest environment.
Out-of-bounds kernel memory read and GPU use-after-free in Imagination Technologies Graphics DDK exposes systems to kernel memory disclosure and potential arbitrary page corruption by local, non-privileged users. Incorrect array index validation in the GPU driver stack allows crafted GPU system calls to bypass kernel memory safety boundaries, resulting in both information disclosure (kernel memory read) and high-availability impact (UAF of arbitrary GPU-managed pages). No public exploit code or active exploitation has been identified; EPSS sits at 0.14% (4th percentile), indicating very low current exploitation probability.
Kernel null pointer dereference in Imagination Technologies Graphics DDK allows a local non-privileged user to crash the host system via crafted GPU system calls. Multiple release branches are affected, including DDK 26.1 RTM1, 25.1-25.3 RTM, 24.2 RTM2, 23.2 RTM2, and 1.18 RTM2. An attacker with a local shell account on a device running the affected kernel driver can trigger platform instability or a full denial of service - no exploit has been publicly identified at time of analysis, and EPSS probability is extremely low at 0.15% (5th percentile).
