    CVE-2026-95702

    Use-after-free vulnerability in VFS in Google gVisor prior to release 20260831.0 on all platforms allows a local attacker with standard container privileges to achieve code execution in the host sentry process by double-freeing the backing MemoryFile from an in-sandbox overlay filesystem. The sentry process remains confined by host-level Linux seccomp and namespace boundaries.
