Technical details
A 32-bit integer overflow occurs during page-to-byte conversion in the KM driver when calculating allocation sizes, resulting in undersized kernel buffer allocation. An attacker running with non-privileged user permissions can conduct improper system calls to trigger the overflow and gain access to unallocated or previously allocated physical pages through an attacker-controlled GPU MMU context, disclosing sensitive kernel data.
