Validate that buffer length fields are non-negative before using them in memory operations in the sockbplog handler. A crafted packet with length -1 (0xFFFFFFFF) could skip allocation and pass a negative size to cdb2buf_fread, causing a segfault. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
