net/url: Insufficient validation of bracketed IPv6 hostnames in net/url

The Parse function permits values other than IPv6 addresses to be included in square brackets within the host component of a URL. RFC 3986 permits IPv6 addresses to be included within the host component, enclosed within square brackets. For example: "http://::1/". IPv4 addresses and hostnames mus...

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...

In the Linux kernel, the following vulnerability has been resolved: udptunnel: fix NULL deref caused by udpsockcreate6 when CONFIGIPV6=n When CONFIGIPV6 is disabled, the udpsockcreate6 function returns 0 success without actually creating a socket. Callers such as foucreate then proceed to...

CVE-2026-23442

The CVE-2026-23442 issue affects the Linux kernel’s IPv6 SRv6 handling. Specifically, __in6_dev_get() may return NULL when a device has no IPv6 configuration (e.g., MTU too small or after NETDEV_UNREGISTER), which could lead to NULL pointer dereferences in seg6_hmac_validate_skb() and ipv6_srh_rc...
