CVE-2020-0069
HIGH ⌖ ON CISA KEV · EXPLOITEDMediaTek chipsets suffered an out-of-bounds write vulnerability that enabled privilege escalation when chained with other known CVEs.
MediaTek chipsets contained insufficient input validation and missing SELinux restrictions in Command Queue drivers, leading to an out-of-bounds write that allowed privilege escalation. DIB organizations must ensure hardware vendors proactively patch known vulnerabilities and implement robust input validation to prevent attackers from chaining exploits for system compromise. This failure highlights the risk of relying on unpatched hardware components in critical infrastructure.
Shame score — The vulnerability was actively exploited in the wild (KEV) and chained with other known CVEs, indicating a lack of timely patching and defensive depth.
▸ RECOMMENDED ACTION Actively exploited (CISA KEV) — remediate now, ahead of your normal patch cycle.
Multiple MediaTek chipsets contain an insufficient input validation vulnerability and have missing SELinux restrictions in the Command Queue drivers ioctl handlers. This causes an out-of-bounds write leading to privilege escalation. This vulnerability was observed chained with CVE-2019-2215 and CVE-2020-0041 under exploit chain "AbstractEmu."
