CVE-2019-15031

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 an interrupt. 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 MSR_TM_ACTIVE is
misused in arch/powerpc/kernel/process.c.
Ubuntu-Description
It was discovered that the Linux kernel on PowerPC architectures did not
properly handle exceptions on interrupts in some situations. A local
attacker could use this to expose sensitive information.
