In the Linux kernel, the following vulnerability has been resolved:
crypto: ccp - Fix use-after-free on error path
In the error path of sev_tsm_init_locked(), the code dereferences 't' after it has been freed with kfree(). The pr_err() statement attempts to access t->tio_en and t->tio_init_done after the memory has been released.
Move the pr_err() call before kfree(t) to access the fields while the memory is still valid.
