CVE-2019-25160 Information

Description

In the Linux kernel the following vulnerability has been resolved:

netlabel: fix out-of-bounds memory accesses

There are two array out-of-bounds memory accesses one in cipso_v4_map_lvl_valid() the other in netlbl_bitmap_walk(). Both errors are embarassingly simple and the fixes are straightforward.

As a FYI for anyone backporting this patch to kernels prior to v4.8 you’ll want to apply the netlbl_bitmap_walk() patch to cipso_v4_bitmap_walk() as netlbl_bitmap_walk() doesn’t exist before Linux v4.8.
