CVE-2026-15893

CVE-2026-15893 affects the Zephyr RTOS IPv6 Neighbor Discovery stack. The function net_if_ipv6_calc_reachable_time() in subsys/net/ip/net_if.c computes a randomized reachable time from base_reachable_time using integer division. When the Reachable Time field of an incoming Router Advertisement is...

CVE-2020-16898: “Bad Neighbor” CVSS Score: 8.8 CVSS Vector: CVSS3.0/AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C Overview On October 13, Microsoft announced an exceptionally critical vulnerability in the Windows IPv6 stack, which allows an attacker to send maliciously crafted packets to...

CVE-2026-17255

IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to cause a denial of service due to improper validation of the prefix length in ICMPv6 Router Advertisements...

CVE-2026-74598

A flaw was found in the Linux kernel's IPv6 networking stack. An off-by-one error in the validation of the Route Information option length RFC 4191 allows a remote attacker to craft a Router Advertisement RA packet. This crafted packet can cause the kernel to read up to 8 bytes beyond the intende...

Astra Linux – Vulnerability in libndp

A vulnerability was discovered in libndp. This flaw allows a local malicious user to trigger a buffer overflow in NetworkManager, by sending a malformed IPv6 router advertisement packet. This issue occurred because libndp did not properly validate the route length information...

In the Linux kernel, the following vulnerability has been resolved: ipv6: fix Route Information option length validation rt6routercv validates the Route Information option RFC 4191 length against the prefix length, but both checks are off by one. rinfo-length is the ND option length in units of 8...

CVE-2026-12633 Out-of-bounds write in IPv6 6LoWPAN Context Option handling via unauthenticated Router Advertisement

The IPv6 neighbor-discovery code in subsys/net/ip/ipv6nbr.c processes the 6LoWPAN Context Option 6CO, RFC 6775 carried inside ICMPv6 Router Advertisements. In handlera6co the 8-bit contextlen field is taken directly from the packet and was never bounded to the RFC maximum of 128. The function...

CVE-2026-12633

CVE-2026-12633 is an out-of-bounds write in the Zephyr RTOS IPv6 neighbor-discovery code (subsys/net/ip/ipv6_nbr.c). The function handle_ra_6co() processes the 6LoWPAN Context Option (RFC 6775) from ICMPv6 Router Advertisements without bounding the 8-bit context_len field to the RFC maximum of 12...
