Описание
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.
