CVE-2024-58008

KEYS: trusted: dcp: fix improper sg use with CONFIG_VMAP_STACK=y

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

KEYS: trusted: dcp: fix improper sg use with CONFIG_VMAP_STACK=y

With vmalloc stack addresses enabled (CONFIG_VMAP_STACK=y) DCP trusted
keys can crash during en- and decryption of the blob encryption key via
the DCP crypto driver. This is caused by improperly using sg_init_one()
with vmalloc'd stack buffers (plain_key_blob).

Fix this by always using kmalloc() for buffers we give to the DCP crypto
driver.
