Summary

Important: kernel-rt security and bug fix update

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 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)

CVE-2023-2235 (GCVE-0-2023-2235)

Vulnerability from cvelistv5 – Published: 2023-05-01 12:51 – Updated: 2025-03-05 19:03

Title

Use-after-free in Linux kernel's Performance Events subsystem

Summary

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.

Severity ?

7.8 (High)

CVE-2023-2194 (GCVE-0-2023-2194)

Vulnerability from cvelistv5 – Published: 2023-04-20 00:00 – Updated: 2025-04-23 16:22

Summary

An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The userspace "data->block[0]" variable was not capped to a number between 0-255 and was used as the size of a memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to crash the system or potentially achieve code execution.

Severity ?

6.7 (Medium)
