CVE-2024-27013

5.5 · MEDIUM
Published May 1, 2024 linux CWE-770 EPSS 0.27% (19th pctl)

Overview

CVE-2024-27013 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 1, 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:

tun: limit printing rate when illegal packet received by tun dev

vhost_worker will call tun call backs to receive packets. If too many

illegal packets arrives, tun_do_read will keep dumping packet contents.

When console is enabled, it will costs much more cpu time to dump

packet and soft lockup will be detected.

net_ratelimit mechanism can be used to limit the dumping rate.
