About this tag
CVE-2026-31637 is a Linux kernel vulnerability in the RxRPC security path, specifically within the rxkad authentication code. The issue occurs when the kernel attempts to decrypt an RxKAD response ticket but continues parsing the ticket buffer even if decryption fails. A malformed RxRPC RESPONSE packet can provide a ticket length not aligned to the cipher block size, leading to a potential security flaw. This tag covers discussions and fixes related to this vulnerability, including patches that ensure proper error handling during ticket decryption. The content is relevant for Linux system administrators and developers working with kernel security and RxRPC protocol implementations.
