CVE-2016-5828 (retired)

Priority
Description
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.
Ubuntu-Description
Cyril Bur discovered that on PowerPC platforms, the Linux kernel mishandled
transactional memory state on exec(). A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code.
