CVE-2026-53267

A flaw was found in the Linux kernel's netfilter subsystem. A local attacker can exploit this vulnerability by creating specially crafted netfilter rules. This can lead to a memory corruption issue, where data on the kernel's memory stack is overwritten. Successful exploitation could result in...

CVE-2026-49943

A flaw was found in the BIRD Internet Routing Daemon. An established BGP Border Gateway Protocol peer can send a specially crafted BGP UPDATE message containing an unusually long ASPATH Autonomous System Path attribute. When a BIRD filter evaluates an AS path mask expression, this can lead to a...

GHSA-CJ9G-3MJ2-G8VV MessagePack-CSharp: JSON conversion APIs can recurse without consistent depth enforcement

Summary MessagePack-CSharp's JSON conversion helpers contain multiple recursion paths that do not consistently enforce a depth limit. These paths are in the JSON conversion component rather than normal typed MessagePack deserialization. Three related issues are covered by this advisory: 1...

UBUNTU-CVE-2026-56766

Hydra through 9.7, fixed in commit 9cc84c2, contains a stack buffer overflow in NTLM authentication across SMTP, POP3, IMAP, NNTP, HTTP, HTTP-Proxy, and HTTP-Proxy-Urlenum modules when processing malicious NTLM Type-2 challenges. A malicious server can send a crafted NTLM Type-2 challenge with an...
