CVE-2026-80646

CVE-2026-80646 affects the Linux kernel ipv6 subsystem. The vulnerability resides in __in6_dev_stats_get(), where a call to dev_get_by_index_rcu() may return NULL if the original physical device has been unregistered, leading to a NULL pointer dereference and a denial of service. The CVSS 3.1 sco...
