Description:
 In the Linux kernel through 5.2.14 on the powerpc platform, a local user
 can read vector registers of other users' processes via a Facility
 Unavailable exception. To exploit the venerability, a local user starts a
 transaction (via the hardware transactional memory instruction tbegin) and
 then accesses vector registers. At some point, the vector registers will be
 corrupted with the values from a different local Linux process because of a
 missing arch/powerpc/kernel/process.c check.
Ubuntu-Description:
 It was discovered that the Linux kernel on PowerPC architectures did not
 properly handle Facility Unavailable exceptions in some situations. A local
 attacker could use this to expose sensitive information.
