{"id":"CVE-2019-15030","details":"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.","modified":"2026-03-12T23:02:16.469420Z","published":"2019-09-13T13:15:11.493Z","related":["SUSE-SU-2019:2412-1","SUSE-SU-2019:2414-1","SUSE-SU-2019:2424-1","SUSE-SU-2019:2648-1","SUSE-SU-2019:2651-1","SUSE-SU-2019:2658-1","SUSE-SU-2019:2738-1","SUSE-SU-2019:2756-1","SUSE-SU-2019:3200-1","SUSE-SU-2020:0093-1","openSUSE-SU-2019:2173-1","openSUSE-SU-2019:2181-1","openSUSE-SU-2024:10728-1","openSUSE-SU-2024:13704-1"],"references":[{"type":"ADVISORY","url":"https://usn.ubuntu.com/4135-2/"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0740"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20191004-0001/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4135-1/"},{"type":"FIX","url":"http://www.openwall.com/lists/oss-security/2019/09/10/3"},{"type":"FIX","url":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8205d5d98ef7f155de211f5e2eb6ca03d95a5a60"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2019-15030.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"5.2.14"}]},{"events":[{"introduced":"0"},{"last_affected":"16.04"}]},{"events":[{"introduced":"0"},{"last_affected":"18.04"}]},{"events":[{"introduced":"0"},{"last_affected":"19.04"}]},{"events":[{"introduced":"0"},{"last_affected":"15.0"}]},{"events":[{"introduced":"0"},{"last_affected":"15.1"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L"}]}
