CVE-2026-7656

The CVE affects Zephyr’s IPv6 Neighbor Discovery in subsys/net/ip/ipv6_nbr.c (handle_ra_input/handle_ns_input/handle_na_input). A faulty boolean combining ND validity checks with ICMPv6 code allowed any ND message with code 0 to bypass Hop Limit==255 and multicast/RS/RA validation, enabling forge...

PT-2026-53753

Name of the Vulnerable Software and Affected Versions Zephyr versions prior to 4.4.0 Description An input validation weakness exists in the IPv6 Neighbor Discovery handlers within subsys/net/ip/ipv6 nbr.c. The functions handle ra input, handle ns input, and handle na input use an incorrect boolea...

CVE-2026-52981

A flaw was found in the Linux kernel. The neighxmit function, when called with an uninitialized neighbor table such as NEIGHNDTABLE when IPv6 is disabled, can return an error without properly releasing the allocated skb socket buffer. This can lead to a memory leak, potentially impacting system...

CVE-2026-53182

A flaw was found in the Linux kernel's nl80211 Wi-Fi subsystem. The nl80211parsernrelems function, responsible for parsing EMA RNR Enhanced Multiple Access Reduced Neighbor Report lists, does not properly handle an excessive number of nested NL80211ATTREMARNRELEMS inputs. This improper input...
