CVE-2019-9445

Published: 6 September 2019

In the Android kernel in F2FS driver there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with system execution privileges needed. User interaction is not needed for exploitation.

From the Ubuntu security team

It was discovered that the F2FS file system in the Linux kernel did not properly perform bounds checking in some situations, leading to an out-of- bounds read. A local attacker could possibly use this to expose sensitive information (kernel memory).

Priority

Low

CVSS 3 base score: 4.4
