Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> KEYS: trusted: dcp: fix improper sg use with CONFIG_VMAP_STACK=y<br /> <br /> With vmalloc stack addresses enabled (CONFIG_VMAP_STACK=y) DCP trusted<br /> keys can crash during en- and decryption of the blob encryption key via<br /> the DCP crypto driver. This is caused by improperly using sg_init_one()<br /> with vmalloc&amp;#39;d stack buffers (plain_key_blob).<br /> <br /> Fix this by always using kmalloc() for buffers we give to the DCP crypto<br /> driver.
