Description
A vulnerability in the Linux kernel's ovpn module involves unsafe in-place updates of the local endpoint bind structure, leading to potential torn reads of IPv6 addresses during concurrent updates. This issue has been resolved by replacing the bind structure when learning a new local endpoint, ensuring safe publication and synchronization.
