Important: kernel security and bug fix update

The kernel packages contain the Linux kernel, the core of any Linux operating system. 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. Bug Fix(es): * Fix max integer mmu_invalidate_seq hanging vCPU (ALBZ#445) * Random delay receiving packets after bringing up VLAN on top of VF with vf-vlan-pruning enabled (BZ#2240750) * bpf_jit_limit hit again (BZ#2243011) * HPE Edgeline 920t resets during kdump context when ice driver is loaded and when system is booted with intel_iommu=on iommu=pt (BZ#2244625)
