CVE-2026-46039 Details
Description
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 potential integer overflow vulnerability has been identified in the Linux kernel's RXGK token length verification process. This issue arises in the 'rxgk_extract_token()' function, where the length of the ticket is checked. The vulnerability exists because the function rounds up the value being tested, which could lead to an overflow. Instead, it should round down the size of the available data to prevent this risk. This vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree, where this vulnerability has been addressed.
