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.

gvisor.dev/gvisor: gVisor: Arbitrary code execution via use-after-free in VFS
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.
A flaw was found in Google gVisor's Virtual File System (VFS). A local attacker with standard container privileges can exploit this vulnerability to achieve arbitrary code execution within the host sentry process. By improperly releasing a backing memory file multiple times from an in-sandbox overlay filesystem, the attacker triggers a us
