CVE-2026-19199

Severity not reported

Data quality: partial. Some fields were not provided by the source.

Software installed and run as a non-privileged user may conduct improper system calls to allocate physical memory.

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.
