ALSA-2023:3708 — Important: kernel-rt security and bug fix update

Affected: AlmaLinux:9: kernel-rt, AlmaLinux:9: kernel-rt-core, AlmaLinux:9: kernel-rt-debug, AlmaLinux:9: kernel-rt-debug-core, AlmaLinux:9: kernel-rt-debug-devel, AlmaLinux:9: kernel-rt-debug-kvm, AlmaLinux:9: kernel-rt-debug-modules, AlmaLinux:9: kernel-rt-debug-modules-core, AlmaLinux:9: kernel-rt-debug-modules-extra, AlmaLinux:9: kernel-rt-devel and 4 more

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 vulnerability in the perf_group_detach function of the Linux Kernel Performance Events (CVE-2023-2235) * kernel: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege escalation (CVE-2023-32233) * Kernel: bluetooth: Unauthorized management command execution (CVE-2023-2002) * kernel: OOB access in the Linux kernel's XFS subsystem (CVE-2023-2124) * kernel: i2c: out-of-bounds write in xgene_slimpro_i2c_xfer() (CVE-2023-2194) * kernel: tls: race condition in do_tls_getsockopt may lead to use-after-free or NULL pointer dereference (CVE-2023-28466)

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.

Bug Fix(es):

* [RT] Single Node Openshift cluster becomes unreachable after running less than 2 hours (BZ#2186853) * kernel-rt: update RT source tree to the latest AlmaLinux-9.2.z1 Batch (BZ#2188313)

A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve local privilege escalation.

The perf_group_detach function did not check the event's siblings' attach_state before calling add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability.

We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2.
