Overview

CVE-2024-50157 is a medium-severity vulnerability. It was published on November 7, 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:

RDMA/bnxt_re: Avoid CPU lockups due fifo occupancy check loop

Driver waits indefinitely for the fifo occupancy to go below a threshold

as soon as the pacing interrupt is received. This can cause soft lockup on

one of the processors, if the rate of DB is very high.

Add a loop count for FPGA and exit the __wait_for_fifo_occupancy_below_th

if the loop is taking more time. Pacing will be continuing until the

occupancy is below the threshold. This is ensured by the checks in

bnxt_re_pacing_timer_exp and further scheduling the work for pacing based

on the fifo occupancy.

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.

How can CyberStrike help with CVE-2024-50157?

CyberStrike is an open-source, AI-augmented pentesting engine.
