Overview

CVE-2022-48777 is a medium-severity vulnerability. It was published on July 16, 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:

mtd: parsers: qcom: Fix kernel panic on skipped partition

In the event of a skipped partition (case when the entry name is empty)

the kernel panics in the cleanup function as the name entry is NULL.

Rework the parser logic by first checking the real partition number and

then allocate the space and set the data for the valid partitions.

The logic was also fundamentally wrong as with a skipped partition, the

parts number returned was incorrect by not decreasing it for the skipped

partitions.

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.
