CVE-2026-13351

Zephyr’s IPv6 network stack is vulnerable to a denial-of-service caused by fragmented IPv6 packets. In the fragment-header processing path, the RX network packet buffer allocated from a memory slab is not released back to the pool after handling malicious fragments. Repeating such packets exhaust...

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...
