Note: Versions mentioned in the description apply only to the upstream kernel-debug package and not the kernel-debug package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

A flaw was found in the Linux Kernel where an attacker may be able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect() and close() function may allow an attacker using the AF_VSOCK protocol to gather a 4 byte information leak or possibly intercept or corrupt AF_VSOCK messages destined to other clients.
