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. 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 nvmet_tcp_free_crypto in NVMe (CVE-2023-5178) * kernel: use-after-free due to race condition occurring in dvb_register_device() (CVE-2022-45884) * kernel: use-after-free due to race condition occurring in dvb_net.c (CVE-2022-45886) * kernel: use-after-free due to race condition occurring in dvb_ca_en50221.c (CVE-2022-45919) * kernel: use-after-free in smb2_is_status_io_timeout() (CVE-2023-1192) 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.
