CVE-2026-10822 is an assertion-failure denial-of-service vulnerability in BIND 9 handling of malformed KEY-family records. BIND accepts and stores a KEY or DNSKEY record using the PRIVATEDNS algorithm (253) when its algorithm-identifier length declares more data than is actually present. If BIND subsequently renders the stored record as text, processing uses the invalid length and triggers an internal consistency check failure, which can abort the named process. Affected releases include BIND 9.18.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.18.11-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.24-S1. Unexpected-exit behavior is confirmed for the 9.20 and 9.21 branches; 9.18 shares the vulnerable code path, although equivalent exit behavior was not confirmed.
