Summary
The affected software is the GPU driver development kit's kernel-mode driver, which handles GPU memory allocation for applications. An attacker running non-privileged software could trigger a miscalculated memory size that leads to an undersized kernel buffer, potentially exposing sensitive kernel memory contents.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
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.
