Summary
KEYS: trusted: Do not use WARN when encode fails
Details

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

KEYS: trusted: Do not use WARN when encode fails

When asn1encodesequence() fails, WARN is not the correct solution.

  1. asn1encodesequence() is not an internal function (located in lib/asn1_encode.c).
  2. Location is known, which makes the stack trace useless.
  3. Results a crash if paniconwarn 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.
