CVE-2026-43099

The CVE-2026-43099 issue affects the Linux kernel, specifically the IPv4/ICMP path and the IPv6 stub handling. When the IPv6 stack is not active (CONFIG_IPV6=m and not loaded), ipv6_dev_find() may return ERR_PTR(-EAFNOSUPPORT); passing that to dev_hold() can cause a null pointer dereference and a...
