Summary
Red Hat Security Advisory: kernel-rt security update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.4 Telecommunications Update Service, and Red Hat Enterprise Linux 8.4 Update Services for SAP Solutions.
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: bpf: Incorrect verifier pruning leads to unsafe code paths being incorrectly marked as safe (CVE-2023-2163)
* kernel: tun: bugs for oversize packet when napi frags enabled in tun_napi_alloc_frags (CVE-2023-3812)
* kernel: use after free in unix_stream_sendpage (CVE-2023-4622)
* kernel: net/sched: sch_hfsc UAF (CVE-2023-4623)
* kernel: use-after-free in sch_qfq network scheduler (CVE-2023-4921)
* kernel: netfilter: potential slab-out-of-bound access due to integer underflow (CVE-2023-42753)
* kernel: IGB driver inadequate buffer size for frames larger than MTU (CVE-2023-45871)
* hw: Intel: Gather Data Sampling (GDS) side channel vulnerability (CVE-2022-40982)
* kernel: UAF during login when accessing the shost ipaddress (CVE-2023-2162)
* kernel: fbcon: out-of-sync arrays in fbcon_mode_deleted due to wrong con2fb_map assignment (CVE-2023-38409)
* kernel: use-after-free in smb2_is_status_io_timeout() (CVE-2023-1192)

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().
