In the Linux kernel, the following vulnerability has been resolved: rxgk: Fix potential integer overflow in length check Fix potential integer overflow in rxgk_extract_token() when checking the length of the ticket. Rather than rounding up the value to be tested (which might overflow), round down the size of the available data.

A flaw was found in the Linux kernel. A potential integer overflow in the `rxgk_extract_token()` function, specifically during the length check of a ticket, could occur. This issue arises from rounding up the value to be tested, which might lead to an overflow. This could potentially result in unpredictable system behavior or a denial of service.
