CVE-2026-62309 CoreDNS: proxyproto plugin panics on PPv2 datagram with non-UDP transport — single 28-byte packet remote DoS

CoreDNS is a DNS server written in Go. Prior to 1.14.4, a single 28-byte UDP datagram can crash the CoreDNS process when the proxyproto plugin is enabled because plugin/pkg/proxyproto/proxyproto.go PacketConn.ReadFrom handles a PROXY v2 header with non-UDP transport such as family byte 0x11,...

CVE-2026-47703

Summary: CVE-2026-47703 affects AdGuard Home and its DoQ-to-UDP forwarding path. Prior to version 0.107.75, the backend UDP path could collapse the DNS transaction ID (txid) to 0 on client-triggered DoQ queries, reducing the entropy of the backend tuple from (txid, source-port) to only the source...

USN-8548-1 linux-aws, linux-fips, linux-lts-xenial vulnerabilities

It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-43503 Several security issues...

CVE-2026-10846

A flaw was found in ldns. When applications use ldns as a resolver over User Datagram Protocol UDP, it fails to properly match the query's destination address and port with the response's source address and port. Additionally, the query ID and question are not matched with the response. This...

JLSEC-2026-718 Heap buffer overflow in DTLS 1.3 ACK message processing

Heap buffer overflow in DTLS 1.3 ACK message processing. A remote attacker can send a crafted DTLS 1.3 ACK message that triggers a heap buffer overflow...

JLSEC-2026-753 A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer...

A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer is authenticated. The buffer overflow was due to an integer truncation when computing the length of the ACK record-number list, causing an undersized buffer to be allocated and then overrun. This...
