CPU exhaustion during message encoding due to O(n²) name compression

During message encoding, hickory-proto's BinEncoder stores pointers to labels that are candidates for name compression in a Vec. The name compression logic then searches for matches with a linear scan. A malicious message with many records can both introduce many candidate labels, and invoke this...

CVE-2026-31682

CVE-2026-31682 affects the Linux kernel bridge implementation, where br_nd_send may parse non-linear ND options from ns->opt[]. The root cause is failure to linearize the skb before ND option parsing, risking reads past the buffer and potential memory exposure or crash. The fix is to linearize...
