Overview

CVE-2022-48630 is a medium-severity vulnerability. It was published on March 5, 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:

crypto: qcom-rng - fix infinite loop on requests not multiple of WORD_SZ

The commit referenced in the Fixes tag removed the 'break' from the else

branch in qcom_rng_read(), causing an infinite loop whenever 'max' is

not a multiple of WORD_SZ. This can be reproduced e.g. by running:

kcapi-rng -b 67 >/dev/null

There are many ways to fix this without adding back the 'break', but

they all seem more awkward than simply adding it back, so do just that.

Tested on a machine with Qualcomm Amberwing processor.

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.
