Summary

The start_thread function in arch/powerpc/kernel/process.c in the Linux kernel through 4.6.3 on powerpc platforms mishandles transactional state, which allows local users to cause a denial of service (invalid process state or TM Bad Thing exception, and system crash) or possibly have unspecified other impact by starting and suspending a transaction before an exec system call.

Exploit prediction (EPSS)

0.45% probability of exploitation in the next 30 days, higher than 39% of all scored CVEs.
