kernel: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold

A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. The scorecvframe function fails to properly hold a reference to a socket after releasing a lock. This oversight allows a concurrent operation to free the socket while it is still being...

CVE-2026-46158

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. When an ADDADDR message is retransmitted, a socket reference count may not be properly decreased, leading to a potential resource leak. Over time, this resource exhaustion could allow a remote attacker to cause a Denial of...

CVE-2026-46170

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. When an ADDADDR message is retransmitted, an issue in socket sk reference counting can prevent the socket from being properly freed. This improper resource management may lead to a Denial of Service DoS condition, where th...

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...
