In the Linux kernel, the following vulnerability has been resolved:
KEYS: trusted: Do not use WARN when encode fails
When asn1_encode_sequence() fails, WARN is not the correct solution.

asn1_encode_sequence() is not an internal function (located
in lib/asn1_encode.c).
Location is known, which makes the stack trace useless.
Results a crash if panic_on_warn is set.
It is also noteworthy that the use of WARN is undocumented, and it
should be avoided unless there is a carefully considered rationale to
use it.
Replace WARN with pr_err, and print the return value instead, which is
only useful piece of information.
