CVE-2026-55602

A flaw was found in http-proxy-middleware before 2.0.10, 3.0.6, and 4.1.0. Router proxy-table host+path matching uses unanchored substring comparison on the Host header, so a crafted Host value that superstring-matches a configured key can route requests to an unintended backend...

CVE-2026-52926

A flaw was found in the Linux kernel's batman-adv module, which is responsible for managing mesh networks. When a mesh network is being shut down, the system fails to properly clear the active gateway information. This leaves outdated network configuration data, which can prevent the mesh network...

CVE-2026-52925

A flaw was found in the Linux kernel's Virtual Routing and Forwarding VRF functionality. When a network device is removed from a VRF, a lack of proper synchronization can lead to a Null Pointer Dereference NPD. This issue can be triggered by a local user, potentially causing the system to crash,...

CVE-2026-53012

CVE-2026-53012 affects the Linux kernel: when an IPv6 nexthop is replaced with an IPv4 nexthop, the has_v4 flag in groups containing that nexthop is not updated. The reverse direction (AF_INET6 to AF_INET) is missed, enabling a stale has_v4=false to bypass fib6_check_nexthop and may cause a NULL ...
