The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * kernel: insufficient input validation in kernel mode driver in Intel i915 graphics leads to privilege escalation * kernel: DMA attack using peripheral devices * kernel: infinite loop in update_blocked_averages in kernel/sched/fair.c leading to denial of service * kernel: a NULL pointer dereference in drivers/scsi/megaraid/megaraid_sas_base.c leading to DoS * kernel: use-after-free in drivers/char/ipmi/ipmi_si_intf.c, ipmi_si_mem_io.c, ipmi_si_port_io.c For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
