CVE-2026-96812 is fixed in golang-gvisor-gvisor on 1 platform by DEBIAN-CVE-2026-96812 (version 0.0~20261026.0-1), released September 25, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Improper Exposure of Resource to Wrong Sphere in the host file helper (gofer) in Google gVisor prior to commit 573a9e73cf844f on Linux platforms with CUSE enabled allows a local attacker with container image deployment privileges to achieve root code execution on the host system. By including a /dev/cuse character device node in a container image, opening the device passes through to the host, allowing the sandboxed attacker to register a host device and exploit CUSE unrestricted ioctl handling to overwrite root udev helper memory.
