Summary
Red Hat Security Advisory: kernel-rt security update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 7.
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-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.
Security Fix(es):
* kernel: use after free in unix_stream_sendpage (CVE-2023-4622)
* kernel: race condition in VT_RESIZEX ioctl when vc_cons[i].d is already NULL leading to NULL pointer dereference (CVE-2020-36558)
* kernel: bluetooth: Unauthorized management command execution (CVE-2023-2002)
* kernel: net/sched: sch_hfsc UAF (CVE-2023-4623)
* kernel: irdma: Improper access control (CVE-2023-25775)
Bug Fix(es):
* kernel-rt: Update RT source tree to the latest RHEL-7.9z30 batch [rhel-7.9.z] (JIRA:RHEL-26440)
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.

If a class with a link-sharing curve, for example, with the HFSC_FSC flag set, has a parent without a link-sharing curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling pointer that can cause a use-after-free issue.",
