Important: kernel-rt security and bug fix update

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 in l2cap_connect and l2cap_le_connect_req in net/bluetooth/l2cap_core.c (CVE-2022-42896) * kernel: tcindex: use-after-free vulnerability in traffic control index filter allows privilege escalation (CVE-2023-1281) * kernel: Use-after-free vulnerability in the Linux Kernel traffic control index filter (CVE-2023-1829) * kernel: use-after-free vulnerability in the perf_group_detach function of the Linux Kernel Performance Events (CVE-2023-2235) * 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) 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.
