CVE-2019-15030

Priority
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.
