UBUNTU-CVE-2026-97568

In the Linux kernel, the following vulnerability has been resolved: mptcp: syncookies: remember the request backup flag Instead of using an uninitialised bit when copying the info in subflowulpclone. To fix this, no need to extend the joinentry structure: backup is coming from struct...

UBUNTU-CVE-2026-97566

In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: kernel: drop pending ADDADDR when removing ID0 The in-kernel MPTCP path manager can leave a stale ADDADDR announcement entry alive when removing the id 0 endpoint. This happens because the id 0 removal path does not te...

CVE-2026-97568

The Linux kernel contains a vulnerability within the mptcp component related to syncookies. The root cause is the use of an uninitialised bit when copying information in the subflow_ulp_clone() function. To resolve this, the backup flag from struct mptcp_subflow_request_sock is now correctly hand...

CVE-2026-97567

The Linux kernel contains a vulnerability where a race condition can occur between the disconnect() and rtx events within the mptcp component. This race condition can lead to an inconsistent status . The issue is resolved by implementing a synchronous timer stop operation to prevent the concurren...

CVE-2026-97566

The Linux kernel contains a vulnerability in the in-kernel MPTCP path manager where removing the id 0 endpoint fails to tear down pending announcements. This asymmetry between the id 0 path and non-zero id paths leaves a stale ADD_ADDR announcement entry alive. When the path manager later reselec...
