Published Oct 21, 2024 linux CWE-476 EPSS 0.24% (16th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-50058 is a medium-severity vulnerability affecting linux linux_kernel. It was published on October 21, 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:

serial: protect uart_port_dtr_rts() in uart_shutdown() too

Commit af224ca2df29 (serial: core: Prevent unsafe uart port access, part

3) added few uport == NULL checks. It added one to uart_shutdown(), so

the commit assumes, uport can be NULL in there. But right after that

protection, there is an unprotected "uart_port_dtr_rts(uport, false);"

call. That is invoked only if HUPCL is set, so I assume that is the

reason why we do not see lots of these reports.

Or it cannot be NULL at this point at all for some reason :P.

Until the above is investigated, stay on the safe side and move this

dereference to the if too.

I got this inconsistency from Coverity under CID 1585130. Thanks.

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.
