CVE-2020-0427
Published: 17 September 2020
In create_pinctrl of core.c, there is a possible out of bounds read due to a use after free. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-140550171
From the Ubuntu Security Team
Elena Petrova discovered that the pin controller device tree implementation in the Linux kernel did not properly handle string references. A local attacker could use this to expose sensitive information (kernel memory).
