Red Hat Security Advisory: kernel security update

Notes

Topic

An update for kernel is now available for Red Hat Enterprise Linux 7.6 Advanced Update Support. Red Hat Product Security has rated this update as having a security impact of Important. 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 kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: net/sched: sch_qfq component can be exploited if in qfq_change_agg function happens qfq_enqueue overhead (CVE-2023-3611) * kernel: net/sched: Use-after-free vulnerabilities in the net/sched classifiers: cls_fw, cls_u32 and cls_route (CVE-2023-4128, CVE-2023-4206, CVE-2023-4207, CVE-2023-4208) 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.
