Low risk3th percentile - higher than 3% of all known CVEs
Summary
Software 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.
Risk Assessment
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.
Recommendation
Update the GPU driver to a patched version. Restrict unprivileged GPU access.
