3. Description:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
Security Fix(es):
* Kernel: KVM: error in exception handling leads to wrong debug stack value
(CVE-2018-1087)
* Kernel: error in exception handling leads to DoS (CVE-2018-8897)
* Kernel: ipsec: xfrm: use-after-free leading to potential privilege
escalation (CVE-2017-16939)
* kernel: Out-of-bounds write via userland offsets in ebt_entry struct in
netfilter/ebtables.c (CVE-2018-1068)
* kernel: ptrace() incorrect error handling leads to corruption and DoS
(CVE-2018-1000199)
* kernel: guest kernel crash during core dump on POWER9 host
(CVE-2018-1091)
For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.
Red Hat would like to thank Andy Lutomirski for reporting CVE-2018-1087 and
CVE-2018-1000199 and Nick Peterson (Everdox Tech LLC) and Andy Lutomirski
