RHEL 10 : jq (RHSA-2026:16692)

medium Nessus Plugin ID 314383

Synopsis

The remote Red Hat host is missing one or more security updates for jq.

Description

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:16692 advisory.

 jq is a lightweight and flexible command-line JSON processor. jq is like sed for JSON data. You can use it to slice, filter, map, or transform structured data with the same ease that sed, awk, grep, or similar applications allow you to manipulate text.

 Security Fix(es):

 * jq: out-of-bounds read in jv_parse_sized() on error formatting for non-NUL-terminated buffers (CVE-2026-39979)

 * jq: jq: Denial of Service via crafted JSON object causing hash collisions (CVE-2026-40164)

 For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL jq package based on the guidance in RHSA-2026:16692.
