Summary
Red Hat Security Advisory: kernel-rt security and bug fix update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 9.0 Extended 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-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.
Security Fix(es):
* kernel: net/sched: sch_hfsc UAF (CVE-2023-4623)
* kernel: use after free in nvmet_tcp_free_crypto in NVMe (CVE-2023-5178)
* kernel: IGB driver inadequate buffer size for frames larger than MTU (CVE-2023-45871)
* kernel: xfrm_expand_policies() in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice (CVE-2022-36879)
* kernel: null-ptr-deref vulnerabilities in sl_tx_timeout in drivers/net/slip (CVE-2022-41858)
* kernel: use-after-free caused by invalid pointer hostname in fs/cifs/connect.c (CVE-2023-1195)
* kernel: UAF during login when accessing the shost ipaddress (CVE-2023-2162)
* kernel: use after free in vcs_read in drivers/tty/vt/vc_screen.c due to race (CVE-2023-3567)
* kernel: use-after-free in netfilter: nf_tables (CVE-2023-3777)
* kernel: SEV-ES local priv escalation (CVE-2023-46813)
Bug Fix(es):
* kernel-rt: update RT source tree to the latest RHEL-9.0.z Batch 14 (RHEL-17273)

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().
