Local privilege escalation via unchecked memory-sharing ranges
Published Mar 2, 2026 · Updated Mar 2, 2026
Out-of-bounds writes in Android kernel pKVM mem_protect.c allow local users to escalate privileges through invalid memory-sharing ranges. The page-state setters accepted addresses outside RAM and overflowing address-plus-size ranges, allowing MMIO pages to enter host memory-sharing paths. Exploitation requires low local privileges on an affected ARM64 device with pKVM; no user interaction is required, and successful abuse grants higher privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
