Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: TCP: cdg: allows tcpcdgrelease to be called multiple times. It seems that MPTCP can call tcpdisconnect on a flow that is already disconnected. This is generally fine, unless the current congestion control mechanism is CDG, as ...
