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...
