CVE-2023-54145

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> bpf: drop unnecessary user-triggerable WARN_ONCE in verifierl log<br /> <br /> It&amp;#39;s trivial for user to trigger "verifier log line truncated" warning,<br /> as verifier has a fixed-sized buffer of 1024 bytes (as of now), and there are at<br /> least two pieces of user-provided information that can be output through<br /> this buffer, and both can be arbitrarily sized by user:<br /> - BTF names;<br /> - BTF.ext source code lines strings.<br /> <br /> Verifier log buffer should be properly sized for typical verifier state<br /> output. But it&amp;#39;s sort-of expected that this buffer won&amp;#39;t be long enough<br /> in some circumstances. So let&amp;#39;s drop the check. In any case code will<br /> work correctly, at worst truncating a part of a single line output.
