Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mptcp: fixed a race condition related to unaccepted mptcp sockets. When the listener socket that owns the relevant request is closed, it frees the unaccepted subflows, which leads to the later deletion of the paired MPTCP sockets...

kernel: mptcp: fix UaF in listener shutdown

A flaw was found in the Linux kernel's Multipath TCP MPTCP subsystem. An improper cleanup sequence during listener socket shutdown can lead to a use-after-free condition where the kernel accesses socket memory after it has already been released. A local attacker could exploit this vulnerability t...
