CVE-2024-53187Public exploit

Local service interruption via io_pin_pages overflow

Published Dec 27, 2024 · Updated May 11, 2026

Integer overflow in Linux kernel io_uring allows local users to interrupt service through a crafted io_uring_setup request. io_pin_pages adds a user-controlled uaddr value to the requested mapping size without first checking whether the address calculation wraps. Low-privilege local access and io_uring availability are required; the observed failure reaches a kernel warning in the page-pinning path.
