CVE-2026-46170

In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: ADDADDR rtx: free sk if last When an ADDADDR is retransmitted, the sk is held in skresettimer, and released at the end. If at that moment, it was the last reference being held, the sk would not be freed. sockput should...

CVE-2026-46158

In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: ADDADDR rtx: always decrease sk refcount When an ADDADDR is retransmitted, the sk is held in skresettimer. It should then be released in all cases at the end. Some unlikely checks were returning directly instead of...

CVE-2026-46137

In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: ADDADDR rtx: fix potential data-race This mptcppmaddtimer helper is executed as a timer callback in softirq context. To avoid any data races, the socket lock needs to be held with bhlocksock. If the socket is in use,...
