Description: The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2018-17182: An issue was discovered in the Linux kernel The vmacache_flush_all function in mm/vmacache.c mishandled sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations (bnc#1108399). The following non-security bugs were fixed: - x86/fpu: Do not do __thread_fpu_end() if use_eager_fpu() (bnc#1109967). Special Instructions and Notes: Please reboot the system after installing this update. Patch Instructions: To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
