dnsmasq: RRSIG rdlen underflow leading to heap OOB read

A heap out-of-bounds read vulnerability was discovered in dnsmasq's DNSSEC validation. When processing RRSIG records, dnsmasq calculates the signature length by subtracting the fixed field size from the record's declared data length. A crafted RRSIG record with a data length smaller than the fixe...

CVE-2026-12244

NSD (the DNS server) is affected when configured as a secondary for a zone. A primary can crash NSD by sending an AXFR containing a DNS message with a specially crafted SVCB RR whose rdata size is 65512, which causes an (uint16_t) length to overflow while allocating space for the RR wrap (total s...
