CVE-2022-49553

7.8 · HIGH

Published Feb 26, 2025CWE-190EPSS 0.28%

Overview

CVE-2022-49553 is a high-severity vulnerability. It was published on February 26, 2025 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. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

fs/ntfs3: validate BOOT sectors_per_clusters

When the NTFS BOOT sectors_per_clusters field is > 0x80, it represents a

shift value. Make sure that the shift value is not too large before using

it (NTFS max cluster size is 2MB). Return -EVINVAL if it too large.

This prevents negative shift values and shift values that are larger than

the field size.

Prevents this UBSAN error:

UBSAN: shift-out-of-bounds in ../fs/ntfs3/super.c:673:16

shift exponent -192 is negative

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.
