CVE-2026-31641

A flaw was found in the Linux kernel's rxrpc subsystem. An unprivileged local user could exploit an integer overflow vulnerability in the `rxrpc_preparse_xdr_yfs_rxgk()` function. This flaw occurs when processing specially crafted key and ticket lengths, causing an incorrect memory allocation size. Consequently, a heap buffer overflow can occur, potentially leading to arbitrary code execution or a denial of service.
