CVE-2026-19566

Net::CIDR::Set versions before 0.23 for Perl allow memory exhaustion and malformed set ranges via unbounded IPv6 prefix lengths. The encode method accepts any prefix length matching 0|1-90-9 and passes it to width2bits, which builds the mask as '1' x $width + 8, one character per bit. The inc...

CVE-2026-19566

CVE-2026-19566 affects Net::CIDR::Set before v0.23. The vulnerability stems from the encode/width handling of IPv6 prefix lengths, where an unbounded prefix length (including values >128) causes large memory allocations during contains() or add() due to the code creating a mask and unpacking i...

dhcpcd: dhcpcd infinite loop and out-of-bounds read via zero-length IPv6 ND option in Router Advertisement handling

A flaw was found in dhcpcd's IPv6 Neighbor Discovery Router Advertisement processing. A specially crafted IPv6 Router Advertisement containing a zero-length Neighbor Discovery option can bypass validation during packet storage and later be reparsed without adequate validation, causing the parser ...

net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

grafana: Grafana Auth Proxy: Unauthorized access due to incorrect IPv6 allow-list default

A flaw in Grafana's Auth Proxy IPv6 allow-list incorrectly defaults to a broad /32 subnet mask instead of a strict /128. This misconfiguration allows remote attackers to bypass access restrictions, potentially leading to unauthorized access and data manipulation...
