Linux Distros Unpatched Vulnerability : CVE-2026-31696

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - rxrpc: Fix missing validation of ticket length in non-XDR key preparsing In rxrpcpreparse, there are two paths for parsing key payloads: the XDR path for large...

CVE-2026-31696

A flaw was found in the Linux kernel's rxrpc component. An unprivileged user can exploit this by providing an excessively large ticket length during key preparsing. This improper validation leads to an oversized token calculation when the key is subsequently read, triggering a system warning and...

CVE-2026-31696

Summary (CVE-2026-31696) : In the Linux kernel’s rxrpc code, the non-XDR key parsing path (rxrpc_preparse()) lacked a validation check for ticket length, unlike the XDR path. This allowed an unprivileged user to supply a very large ticket length, causing the computed total token size (toksize) to...

CVE-2026-31637

A flaw was found in the Linux kernel's rxrpc subsystem. A remote attacker could exploit this by sending a malformed RXKAD response ticket. This ticket, with a non-block-aligned length, would cause decryption to fail, yet the system would proceed to process attacker-controlled data. This could lea...
