Description:
 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.
Ubuntu-Description:
 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).
