high Tenable Cloud Security Plugin ID 467165

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: crypto: ecc - Fix carry overflow in
vli multiplication The carry flag calculation fails when r01.m_high is saturated (0xFFFFFFFFFFFFFFFF) and
addition of lower bits overflows. The condition (r01.m_high < product.m_high) doesn't handle the case
where r01.m_high == product.m_high and an additional carry exists from lower-bit overflow. When commit
3c4b23901a0c ("crypto: ecdh - Add ECDH software support") introduced crypto/ecc.c, it split the muladd()
function in the micro-ecc library into separate mul_64_64() and add_128_128() helpers. It seems the check
got lost in translation. Add proper handling for this boundary by accounting for the carry from the lower
addition. (CVE-2026-64313)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.528.43 or later.
