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)

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)

A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service.
