UBUNTU-CVE-2025-68240

In the Linux kernel, the following vulnerability has been resolved: nilfs2: avoid having an active sctimer before freeing sci Because kthreadstop did not stop sctask properly and returned -EINTR, the sctimer was not properly closed, ultimately causing the problem 1 reported by syzbot when freeing...

CVE-2025-68291

The CVE-2025-68291 issue affects the Linux kernel MPTCP path: in mptcp_do_fastclose(), rcv_mss was not initialised before triggering tcp_send_active_reset(), leading to a divide-by-zero in __tcp_select_window() for MPTCP sockets. The fix mirrors a prior bare-TCP patch by initialising rcv_mss (to ...

CVE-2025-68291 mptcp: Initialise rcv_mss before calling tcp_send_active_reset() in mptcp_do_fastclose().

In the Linux kernel, the following vulnerability has been resolved: mptcp: Initialise rcvmss before calling tcpsendactivereset in mptcpdofastclose. syzbot reported divide-by-zero in tcpselectwindow by MPTCP socket. 0 We had a similar issue for the bare TCP and fixed in commit 499350a5a6e7 "tcp:...

CVE-2025-68240

The CVE-2025-68240 entry concerns the Linux kernel nilfs2 subsystem. The described vulnerability arose because a sc_timer could remain active when freeing sci, caused by kthread_stop not reliably stopping sc_task (returning -EINTR), leaving the timer improperly closed. The remediation uses timer_...
