The tm_reclaim_thread function in arch/powerpc/kernel/process.c in the Linux kernel before 4.4.1 on powerpc platforms does not ensure that TM suspend mode exists before proceeding with a tm_reclaim call, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application.

kernel: incorrect restoration of machine specific registers from userspace
The tm_reclaim_thread function in arch/powerpc/kernel/process.c in the Linux kernel before 4.4.1 on powerpc platforms does not ensure that TM suspend mode exists before proceeding with a tm_reclaim call, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application.
A flaw was found in the Linux kernel which could cause a kernel panic when restoring machine specific registers on the PowerPC platform. Incorrect transactional memory state registers could inadvertently change the call path on return from userspace and cause the kernel to enter an unknown state and crash.

CVE-2015-8845 CVE-2015-8844 kernel: incorrect restoration of machine specific registers from userspace
A flaw was found in the linux kernel which could cause a kernel panic when restoring machine specific registers on the power pc platform. Incorrect transactional memory state registers could inadvertently change the call path on return from userspace and cause the kernel to enter an unknown state and panic defensively.
The message is usually as follows:
