CVE-2019-15031 (GCVE-0-2019-15031)

Vulnerability from cvelistv5 – Published: 2019-09-13 12:45 – Updated: 2024-08-05 00:34
VLAI?
Summary
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.
