Critical (9.8) in google gvisor. EPSS 0.8% chance of exploitation in the next 30 days.

pkg/sentry/kernel/shm/shm.go in Google gVisor before 2018-11-01 allows attackers to overwrite memory locations in processes running as root (but not escape the sandbox) via vectors involving IPC_RMID shmctl calls, because reference counting is mishandled.
