CVE-2026-46193

A flaw was found in the Linux kernel's xfrm: ah component, which handles network security protocols. When Extended Sequence Number (ESN) is active, the kernel incorrectly processes parts of network packet data during security checks. This error can lead to the system dropping legitimate network traffic. An attacker could potentially exploit this to cause a Denial of Service (DoS), making the affected system unable to communicate over the network.
