CVE-2023-52757

7.8 · HIGH
Published May 21, 2024 debian CWE-416 EPSS 0.19% (8th pctl)

Overview

CVE-2023-52757 is a high-severity vulnerability affecting debian debian_linux. It was published on May 21, 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:

smb: client: fix potential deadlock when releasing mids

All release_mid() callers seem to hold a reference of @mid so there is

no need to call kref_put(&mid->refcount, __release_mid) under

@server->mid_lock spinlock. If they don't, then an use-after-free bug

would have occurred anyways.

By getting rid of such spinlock also fixes a potential deadlock as

shown below

Remediation

Check the references section for vendor advisories and patches from debian. Update debian_linux 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.
