kernel: ipv6: mcast: Fix use-after-free when processing MLD queries

A flaw was found in the Linux kernel's IPv6 multicast mcast component. When processing Multicast Listener Discovery MLD queries, a pointer to the multicast group address is not correctly reloaded after certain packet manipulations. This can lead to a use-after-free vulnerability, potentially...

CVE-2026-53275

CVE-2026-53275 affects the Linux kernel IPv6 multicast path (net/ipv6/mcast.c) during MLD query processing. A pointer to the multicast group address is captured during initial packet parsing but is not reloaded after skb header changes from pskb_may_pull(), leading to a use-after-free in __mld_qu...
