CVE-2026-98102

A flaw was found in the Linux kernel's IPv6 multicast implementation. When removing an active multicast source filter, an internal list pointer is updated before the read-copy update RCU grace period elapses. A local user can exploit this race condition during concurrent multicast address lookups...
