In the Linux kernel, the following vulnerability has been resolved: qede: fix off-by-one in BD ring consumption on buildskb failure qederxbuildskb and qedetparxbuildskb do not check for a NULL return from qedebuildskb. When it returns NULL under memory pressure, the functions still consume a BD...

CVE-2026-49263 Capstone WASM `br_table` instruction-size truncation can cause no-progress disassembly and parser desynchronization

Capstone is a disassembly framework. Prior to version 6.0.0-Alpha9, Capstone's WebAssembly backend accepts attacker-controlled raw WASM instruction bytes through the public csdisasm and csdisasmiter APIs. For a large but well-formed brtable instruction, the WASM decoder accumulates the immediate...

CVE-2026-71324

Traefik is an open source HTTP reverse proxy and load balancer. Prior to 2.11.53, 3.6.24, and 3.7.9, Traefik's default HTTP reverse proxy forwards a plain HTTP/2 or HTTP/3 CONNECT request and its body to an HTTP/1.1 upstream through a shared net/http.Transport. When the upstream answers the CONNE...
