Description

In the Linux kernel, the following vulnerability has been resolved: crypto: omap - Allocate OMAP_CRYPTO_FORCE_COPY scatterlists correctly The existing allocation of scatterlists in omap_crypto_copy_sg_lists() was allocating an array of scatterlist pointers, not scatterlist objects, resulting in a 4x too small allocation. Use sizeof(*new_sg) to get the correct object size.
