The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
Note: This issue is present in hardware and cannot be fully fixed via software update. The updated kernel packages provide software side of the mitigation for this hardware issue. To be fully functional, up-to-date CPU microcode applied on the system is required. Please refer to References section for further information about this issue, CPU microcode requirements and the potential performance impact.
In this update mitigations for x86 (both 32 and 64 bit) architecture are provided.
Red Hat would like to thank Ken Johnson (Microsoft Security Response Center) and Jann Horn (Google Project Zero) for reporting this issue.
Bug Fix(es):
‘WARNING: CPU: 13 PID: 36409 at lib/list_debug.c:59 __list_del_entry+0xa1/0xd0 list_del corruption. prev->next should be ffffdd03fddeeca0, but was (null)’
This update ensures that the code does not corrupt memory. As a result, the operating system no longer hangs. (BZ#1573176)
