In the Linux kernel, the following vulnerability has been resolved:

crypto: bcm - Fix pointer arithmetic

In spu2_dump_omd() value of ptr is increased by ciph_key_len instead of hash_iv_len which could lead to going beyond the buffer boundaries. Fix this bug by changing ciph_key_len to hash_iv_len.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
