Overview

CVE-2024-35793 is a high-severity vulnerability. It was published on May 17, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

debugfs: fix wait/cancellation handling during remove

Ben Greear further reports deadlocks during concurrent debugfs

remove while files are being accessed, even though the code in

question now uses debugfs cancellations. Turns out that despite

all the review on the locking, we missed completely that the

logic is wrong: if the refcount hits zero we can finish (and

need not wait for the completion), but if it doesn't we have

to trigger all the cancellations. As written, we can _never_

get into the loop triggering the cancellations. Fix this, and

explain it better while at it.

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.
