CVE-2015-8845: The tm_reclaim_thread function in arch/powerpc/kernel/process.c in the Linux kernel before 4.4.1 on powerpc...

Security readout for executives and security teams

This is a Linux kernel denial-of-service issue on powerpc systems. A local user running a crafted application could trigger a kernel panic, taking the host down. The sources do not indicate data theft, privilege escalation, remote access, or active exploitation. Exposure is limited to Linux systems running vulnerable powerpc kernels before the fixed upstream change or vendor-backported updates. Non-powerpc systems are not identified as affected in the provided sources. Treat this as a targeted availability risk for legacy or specialized powerpc Linux estates. It is not a broad internet-facing emergency based on the supplied evidence, but unpatched multi-user systems can be taken offline by local users. Mitigation focus: Apply vendor kernel updates from relevant SUSE, openSUSE, or Red Hat advisories.; For upstream kernels, move to a version containing the 4.4.1 fix or later.; Prioritize multi-user powerpc servers and systems running untrusted local workloads..
