Description

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

crypto: ccp - Fix possible deadlock in SEV init failure path

__sev_platform_init_handle_init_ex_path() calls rmp_mark_pages_firmware() with locked=false while the parent function of init_ex_path already acquired the sev_cmd_mutex. In the case of an RMPUPDATE failure for any page after the first, the cleanup path would invoke reclaim pages which would result in a deadlock in sev_do_cmd.

Pass locked=true to honor the lock status of the parent function.
