\nDescription : <\/strong>In the Linux kernel, the following vulnerability has been resolved:<\/p>\n

crypto: caam – Prevent crash on suspend with iMX8QM \/ iMX8ULP<\/p>\n

Since the CAAM on these SoCs is managed by another ARM core, called the
\nSECO (Security Controller) on iMX8QM and Secure Enclave on iMX8ULP, which
\nalso reserves access to register page 0 suspend operations cannot touch
\nthis page.<\/p>\n

This is similar to when running OPTEE, where OPTEE will reserve page 0.<\/p>\n

Track this situation using a new state variable no_page0, reflecting if
\npage 0 is reserved elsewhere, either by other management cores in SoC or
\nby OPTEE.<\/p>\n

Replace the optee_en check in suspend\/resume with the new check.<\/p>\n

optee_en cannot go away as it’s needed elsewhere to gate OPTEE specific
\nsituations.<\/p>\n

Fixes the following splat at suspend:<\/p>\n
