CVE-2026-19199

Not yet rated

Not yet rated — under the NVD policy in effect since April 2026, most CVEs are no longer analyzed immediately. The EPSS score (if available) is still shown.

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.
