CVE-2026-68170
CVE-2026-68170, affecting Linux kernel MPTCP, describes a use-after-free risk caused by a stale backlog backlog entry referencing a closing subflow. The issue arises because backlog cleanup was performed in mptcp_close_ssk() without holding the ssk lock or mptcp_data_lock(), while concurrent RX p...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: mptcp: ensure context reset on disconnect After the committed code below, if the MPC subflow is already in the TCPCLOSE status or has fallen back to TCP at the mptcpdisconnect time, mptcpdofastclose skips setting the sendfastclos...
kernel: mptcp: fix slab-use-after-free in __inet_lookup_established
A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...
