Details

A local privilege escalation was discovered in the Linux kernel before 5.10.13. Multiple race conditions in the AFVSOCK implementation are caused by wrong locking in net/vmwvsock/af_vsock.c. The race conditions were implicitly introduced in the commits that added VSOCK multi-transport support.
