CVE-2024-46745

5.5 · MEDIUM
Published Sep 18, 2024 linux CWE-770 EPSS 0.28% (20th pctl)

Overview

CVE-2024-46745 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 18, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

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

Input: uinput - reject requests with unreasonable number of slots

When exercising uinput interface syzkaller may try setting up device

with a really large number of slots, which causes memory allocation

failure in input_mt_init_slots(). While this allocation failure is

handled properly and request is rejected, it results in syzkaller

reports. Additionally, such request may put undue burden on the

system which will try to free a lot of memory for a bogus request.

Fix it by limiting allowed number of slots to 100. This can easily

be extended if we see devices that can track more than 100 contacts.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
