CVE-2025-1290Network attack vector

Kernel code execution via AF_VSOCK use-after-free

Published Apr 17, 2025 · Updated May 8, 2025

Use-after-free in Google ChromeOS 15474.84.0 with kernel 5.4 allows remote attackers to execute kernel code through AF_VSOCK. The virtio_transport_space_update function accesses a virtio_vsock_sock after concurrent allocation and freeing during a connect syscall leaves a dangling pointer. Successful exploitation requires winning the race; kernel-context execution then grants control of the affected device.
