CVE-2019-0155 – hw: Intel GPU blitter manipulation can allow for arbitrary kernel memory write

https://notcve.org/view.php?id=CVE-2019-0155

Insufficient access control in a subsystem for Intel (R) processor graphics in 6th, 7th, 8th and 9th Generation Intel(R) Core(TM) Processor Families; Intel(R) Pentium(R) Processor J, N, Silver and Gold Series; Intel(R) Celeron(R) Processor J, N, G3900 and G4900 Series; Intel(R) Atom(R) Processor A and E3900 Series; Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and E-2200 Processor Families; Intel(R) Graphics Driver for Windows before 26.20.100.6813 (DCH) or 26.20.100.6812 and before 21.20.x.5077 (aka15.45.5077), i915 Linux Driver for Intel(R) Processor Graphics before versions 5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 may allow an authenticated user to potentially enable escalation of privilege via local access. Un control de acceso insuficiente en un subsistema para Intel® processor graphics en 6th, 7th, 8th and 9th Generation Intel® Core(TM) Processor Families; Intel® Pentium® Processor J, N, Silver y Gold Series; Intel® Celeron® Processor J, N, G3900 y G4900 Series; Intel® Atom® Processor A y E3900 Series; Intel® Xeon® Processor E3-1500 v5 y v6, E-2100 y E-2200 Processor Families; Intel® Graphics Driver para versiones de Windows anteriores a 26.20.100.6813 (DCH) o 26.20.100.6812 y versiones anteriores a 21.20.x.5077 (también se conoce como 15.45.5077), i915 Linux Driver para Intel® Processor Graphics versiones anteriores a 5.4-rc7, 5.3. 11, 4.19.84, 4.14.154, 4.9.201, 4.4.201, puede habilitar a un usuario autenticado para permitir potencialmente una escalada de privilegios por medio de un acceso local. A flaw was found in the Intel graphics hardware (GPU), where a local attacker with the ability to issue commands to the GPU could inadvertently lead to memory corruption and possible privilege escalation. The attacker could use the GPU blitter to perform privilege MMIO operations, not limited to the address space required to function correctly. • http://packetstormsecurity.com/files/155375/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://access.redhat.com/errata/RHSA-2019:3841 https://access.redhat.com/errata/RHSA-2019:3887 https://access.redhat.com/errata/RHSA-2019:3889 https://access.redhat.com/errata/RHSA-2019:3908 https://access.redhat.com/errata/RHSA-2020:0204 https://seclists.org/bugtraq/2019/Nov/26 https://security.netapp.com/advisory/ntap-20200320-0005 https://support.f5.com/csp/article/K73659122 • CWE-284: Improper Access Control •
