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: 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)
