Summary
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.
