Last modified

CVE-2016-5828 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.45% chance of exploitation in the next 30 days.
