Overview

CVE-2024-26828 is a critical-severity vulnerability. It was published on April 17, 2024 and has a CVSS 3.1 base score of 9.4 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.4, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

cifs: fix underflow in parse_server_interfaces()

In this loop, we step through the buffer and after each item we check

if the size_left is greater than the minimum size we need. However,

the problem is that "bytes_left" is type ssize_t while sizeof() is type

size_t. That means that because of type promotion, the comparison is

done as an unsigned and if we have negative bytes left the loop

continues instead of ending.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
