CVE-2026-43284

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...

CVE-2026-33190

CoreDNS TSIG authentication bypass vulnerability (CVE-2026-33190) affects versions prior to 1.14.3 on non-plain-DNS transports. The tsig plugin trusts the transport writer’s TsigStatus() instead of verifying TSIG itself, causing unauthenticated remote access over DoT, DoH, DoH3, DoQ, and gRPC. Do...
