Overview

CVE-2024-35819 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 17, 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:

soc: fsl: qbman: Use raw spinlock for cgr_lock

smp_call_function always runs its callback in hard IRQ context, even on

PREEMPT_RT, where spinlocks can sleep. So we need to use a raw spinlock

for cgr_lock to ensure we aren't waiting on a sleeping task.

Although this bug has existed for a while, it was not apparent until

commit ef2a8d5478b9 ("net: dpaa: Adjust queue depth on rate change")

which invokes smp_call_function_single via qman_update_cgr_safe every

time a link goes up or down.

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.
