A vulnerability was detected in HKUDS nanobot up to 0.2.1. The affected element is the function connectmcpservers of the file nanobot/agent/tools/mcp.py of the component MCP enabledTools Scope Handler. Performing a manipulation results in improper access controls. The attack is possible to be...

CVE-2026-64575

A flaw was found in the Linux kernel. A double release of socket resources can occur during batch reallocation in the BPF Berkeley Packet Filter TCP iterator. A local attacker could exploit this vulnerability to trigger a kernel panic. This leads to a system crash, resulting in a Denial of Servic...

CVE-2026-64575

CVE-2026-64575 affects the Linux kernel’s BPF TCP iterator. The issue is a double release of socket resources during batch reallocation in bpf_iter_tcp_batch, where on realloc failure the code returns ERR_PTR() and leaves cur_sk

In the Linux kernel, the following vulnerability has been resolved: bpf: tcp: fix double sock release on batch realloc bpfitertcpbatch releases the current batch via bpfitertcpputbatch, which drops the socket refs and rewrites each slot with the socket cookie, then grows the batch. cursk/endsk ar...

CVE-2026-45103 OpenSIPS: SIP Message Smuggling via TCP Content-Length Integer Overflow

OpenSIPS is a Session Initiation Protocol SIP server implementation. In versions prior to 3.6.6 and 4.0.0-rc1, the TCP message framing layer parses the Content-Length header using unsigned int arithmetic with no overflow check. When an attacker sends a Content-Length value that overflows unsigned...

CVE-2026-64564

In the Linux kernel, the following vulnerability has been resolved: sctp: don't free the ASCONF's own transport in DEL-IP processing sctpprocessasconf caches the transport the ASCONF chunk is processed against in asconf-transport == chunk-transport, set once in sctprcv. For an ASCONF located...

CVE-2026-64564

CVE-2026-64564 concerns a Linux kernel SCTP DEL-IP processing bug. The vulnerability arises because sctp_process_asconf() caches the ASCONF transport in asconf->transport (tied to chunk->transport) and that transport can be different from the packet source address when looked up via __sctp_...
