AMD beseitigte zahlreiche Sicherheitslücken im Grafiktreiber für Windows 10
In einem in dieser Woche erschienenen Security Bulletin hat AMD insgesamt 27 Sicherheitslücken im Grafiktreiber für Windows 10 aufgeführt, von denen man die meisten bereits im Jahr 2020 beseitigt hat. Zwei davon wurden allerdings erst mit der Version 21.4.1 angegangen und besitzen jeweils die Einstufung “Hoch”.
Es empfiehlt sich also nicht nur wegen der beiden letztgenannten Sicherheitslücken, CVE-2020–12960 und CVE-2020–12981, oder zum Beispiel wegen der Performanceverbesserungen im gestern erschienenen Treiber 21.11.2 diesen aktuell zu halten.
“In a comprehensive analysis of the AMD Escape calls, a potential set of weaknesses in several APIs was discovered, which could result in escalation of privilege, denial of service, information disclosure, KASLR bypass, or arbitrary write to kernel memory.”

CVE-2020–12900 | High | An arbitrary write vulnerability in the AMD Radeon Graphics Driver for Windows 10 potentially allows unprivileged users to gain Escalation of Privileges and cause Denial of Service. |
CVE-2020–12929 | High | Improper parameters validation in some trusted applications of the PSP contained in the AMD Graphics Driver may allow a local attacker to bypass security restrictions and achieve arbitrary code execution. |
CVE-2020–12960 | High | AMD Graphics Driver for Windows 10, amdfender.sys may improperly handle input validation on InputBuffer which may result in a denial of service (DoS). |
CVE-2020–12980 | High | An out of bounds write and read vulnerability in the AMD Graphics Driver for Windows 10 may lead to escalation of privilege or denial of service. |
CVE-2020–12981 | High | An insufficient input validation in the AMD Graphics Driver for Windows 10 may allow unprivileged users to unload the driver, potentially causing memory corruptions in high privileged processes, which can lead to escalation of privileges or denial of service. |
CVE-2020–12982 | High | An invalid object pointer free vulnerability in the AMD Graphics Driver for Windows 10 may lead to escalation of privilege or denial of service. |
CVE-2020–12983 | High | An out of bounds write vulnerability in the AMD Graphics Driver for Windows 10 may lead to escalation of privileges or denial of service. |
CVE-2020–12985 | High | An insufficient pointer validation vulnerability in the AMD Graphics Driver for Windows 10 may lead to escalation of privilege or denial of service. |
CVE-2020–12986 | High | An insufficient pointer validation vulnerability in the AMD Graphics Driver for Windows 10 may cause arbitrary code execution in the kernel, leading to escalation of privilege or denial of service. |
CVE-2020–12962 | Medium | Escape call interface in the AMD Graphics Driver for Windows may cause privilege escalation. |
CVE-2020–12904 | Medium | Out of Bounds Read in AMD Graphics Driver for Windows 10 in Escape 0x3004203 may lead to arbitrary information disclosure. |
CVE-2020–12905 | Medium | Out of Bounds Read in AMD Graphics Driver for Windows 10 in Escape 0x3004403 may lead to arbitrary information disclosure. |
