CVE-2025-21775

EUVD-2025-5147
In the Linux kernel, the following vulnerability has been resolved:

can: ctucanfd: handle skb allocation failure

If skb allocation fails, the pointer to struct can_frame is NULL. This
is actually handled everywhere inside ctucan_err_interrupt() except for
the only place.

Add the missed NULL check.

Found by Linux Verification Center (linuxtesting.org) with SVACE static
analysis tool.
