CVE-2026-63924

A flaw was found in the Linux kernel's handling of IPv6 extended headers. Specifically, the ipv6hopjumbo function, which processes jumbo payloads, can modify internal packet buffer skb pointers. However, the network header nh pointer is not recomputed after these modifications. This oversight cou...

CVE-2026-63912

A flaw was found in the Linux kernel's Encapsulating Security Payload ESP component. This vulnerability occurs in the ESP out-of-place fast path when handling combined single-fragment lengths. An attacker could potentially trigger a scenario where the system rejects the page-fragment fast path,...

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...
