CVE-2026-35091 Corosync: corosync: denial of service and information disclosure via crafted udp packet

A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol UDP packet. This can lead to an out-of-bounds read, causing a denial of service...

Linux Distros Unpatched Vulnerability : CVE-2026-23331

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - udp: Unhash auto-bound connected sk from 4-tuple hash table when disconnected. Let's say we bind an UDP socket to the wildcard address with a non-zero port,...

CVE-2026-23331

A flaw was found in the Linux kernel's handling of User Datagram Protocol UDP sockets. When an auto-bound UDP socket is connected and subsequently disconnected, it may not be properly unhashed from the 4-tuple hash table. This oversight can lead to the accumulation of stale entries, potentially...
