Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> netlabel: fix out-of-bounds memory accesses<br /> <br /> There are two array out-of-bounds memory accesses, one in<br /> cipso_v4_map_lvl_valid(), the other in netlbl_bitmap_walk(). Both<br /> errors are embarassingly simple, and the fixes are straightforward.<br /> <br /> As a FYI for anyone backporting this patch to kernels prior to v4.8,<br /> you&amp;#39;ll want to apply the netlbl_bitmap_walk() patch to<br /> cipso_v4_bitmap_walk() as netlbl_bitmap_walk() doesn&amp;#39;t exist before<br /> Linux v4.8.
