Raw vector
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2020-0069 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Huawei Y6 2019 Firmware. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 29% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The vulnerability is an out-of-bounds write in the ioctl handlers of the Mediatek Command Queue driver within the Android kernel. It stems from insufficient input sanitization combined with missing SELinux restrictions and is tracked under Android ID A-147882143 and CWE-787. The issue affects Android devices using the Mediatek kernel components and carries a CVSS 3.1 score of 7.8.
A local attacker with low privileges can invoke the affected ioctl interfaces to corrupt kernel memory, achieving escalation of privilege to higher levels without requiring user interaction or additional execution rights. This allows full compromise of the kernel's confidentiality, integrity, and availability on the device.
Android security bulletins from March 2020 and related Huawei advisories address the flaw through kernel patches that enforce proper input validation and SELinux policy restrictions. The vulnerability appears in CISA's catalog of known exploited vulnerabilities, confirming observed in-the-wild use.
