Description:
 In f2fs_xattr_generic_list of xattr.c, 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
 required for exploitation.Product: Android. Versions: Android kernel.
 Android ID: A-120551147.
Ubuntu-Description:
 It was discovered that the F2FS file system implementation in the Linux
 kernel did not properly perform bounds checking on xattrs in some
 situations. A local attacker could possibly use this to expose sensitive
 information (kernel memory).
