CVE-2019-0154 – hw: Intel GPU Denial Of Service while accessing MMIO in lower power state

https://notcve.org/view.php?id=CVE-2019-0154

Insufficient access control in 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 and E-2100 Processor Families may allow an authenticated user to potentially enable denial of service via local access. Un control de acceso insuficiente en el subsistema para Intel® processor graphics en 6th, 7th, 8th y 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 y E-2100 Processor Families, puede habilitar a un usuario autenticado para permitir potencialmente una denegación de servicio por medio de un acceso local. A flaw was found in Intel graphics hardware (GPU) where a local attacker with the ability to issue an ioctl could trigger a hardware level crash if MMIO registers were read while the graphics card was in a low-power state. This creates a denial of service situation and the GPU and connected displays will remain unusable until a reboot occurs. • http://packetstormsecurity.com/files/155375/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://access.redhat.com/errata/RHSA-2020:0204 https://seclists.org/bugtraq/2019/Nov/26 https://security.netapp.com/advisory/ntap-20200320-0004 https://support.f5.com/csp/article/K73659122?utm_source=f5support&amp%3Butm_medium=RSS https://usn.ubuntu.com/4186-2 https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00260.html https://access.redhat.com/security/ • CWE-284: Improper Access Control •
