Red Hat Security Advisory: gawk security update
Severity
Moderate
Notes
Topic: An update for gawk is now available for Red Hat Enterprise Linux 9.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: The gawk packages contain the GNU version of awk, a text processing utility. Awk interprets a special-purpose programming language to do quick and easy text pattern matching and reformatting jobs.
Security Fix(es):
* gawk: gawk: Memory corruption via integer overflow (CVE-2026-40468)
* gawk: Gawk: Buffer overflow in ftype() routine may lead to code execution or denial of service (CVE-2026-40553)
* gawk: gawk: Denial of Service due to Use After Free vulnerability in io.c (CVE-2026-40467)
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.
