CVE-2026-49745: CWE - CWE-823: Use of Out-of-range Pointer Offset (4.16) in Imagination Technologies Graphics DDK
Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory. Software installed and run under a Guest VM can send commands to the GPU which result in out of bounds memory accesses. These can be used to escalate privileges.
AI Analysis
Technical Summary
CVE-2026-49745 is a use of out-of-range pointer offset vulnerability (CWE-823) in the Imagination Technologies Graphics DDK. Kernel software inside a Guest VM can post commands to the GPU firmware that trigger writes outside the bounds of the Guest's virtualized GPU memory. This memory corruption can be exploited to escalate privileges within the Guest VM. No CVSS score or detailed vendor remediation information is currently available.
Potential Impact
The vulnerability allows a Guest VM to perform out-of-bounds memory writes to the GPU firmware memory space, potentially enabling privilege escalation within the virtualized environment. This could compromise the isolation between the Guest VM and the host or other VMs, undermining the security of the virtualization platform.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround has been published at this time.
