CVE-2019-15031 – kernel: powerpc: local user can read vector registers of other users' processes via an interrupt
https://notcve.org/view.php?id=CVE-2019-15031
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. En el kernel de Linux versiones hasta 5.2.14 en la plataforma powerpc, un usuario local puede leer los registros vectoriales de los procesos de otros usuarios por medio de una interrupción. Para explotar la venerabilidad, un usuario local inicia una transacción (por medio de la instrucción de memoria transaccional de hardware tbegin) y luego accede a los registros vectoriales. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://www.openwall.com/lists/oss-security/2019/09/10/4 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a8318c13e79badb92bc6640704a64cc022a6eb97 https://security.netapp.com/advisory/ntap-20191004-0001 https://usn.ubuntu.com/4135-1 https://usn.ubuntu.com/4135-2 https://access.redhat.com/security/cve/CVE-2019 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-662: Improper Synchronization •
CVE-2019-15030 – kernel: powerpc: local user can read vector registers of other users' processes via a Facility Unavailable exception
https://notcve.org/view.php?id=CVE-2019-15030
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. En el kernel de Linux versiones hasta 5.2.14 en la plataforma powerpc, un usuario local puede leer registros vectoriales de los procesos de otros usuarios por medio de una excepción Facility Unavailable. Para explotar la venerabilidad, un usuario local inicia una transacción (por medio de la instrucción de memoria transaccional de hardware tbegin) y entonces accede a los registros vectoriales. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://www.openwall.com/lists/oss-security/2019/09/10/3 https://access.redhat.com/errata/RHSA-2020:0740 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8205d5d98ef7f155de211f5e2eb6ca03d95a5a60 https://security.netapp.com/advisory/ntap-20191004-0001 https://usn.ubuntu.com/4135-1 https://usn.ubuntu.com/4135-2& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-862: Missing Authorization •
