Vulnerability Details CVE-2026-23344
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.
