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...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: NET: bonding: Fixed a NULL dereference of the ndtbl variable when IPv6 is disabled. When booting with the ‘ipv6.disable=1’ parameter, the ndtbl is never initialized because inet6init exits before ndiscinit is called, which...

Astra Linux – Vulnerability in edk2

EDK2’s Network Package is vulnerable to an out-of-bounds read vulnerability when processing the Neighbor Discovery Redirect message. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially result in a loss of confidentiality...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bridge: brndsend: Linearize the skb before parsing ND options. The brndsend function parses neighbor discovery options from ns-opt and assumes that these options are located in the linear part of the request. Its callers only...

PT-2026-91392

When base reachable ti...

Linux Kernel MCTP Routing Uninitialized Memory Information Disclosure Vulnerability

This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handlin...

CVE-2026-12633

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...

dhcpcd: dhcpcd infinite loop and out-of-bounds read via zero-length IPv6 ND option in Router Advertisement handling

A flaw was found in dhcpcd's IPv6 Neighbor Discovery Router Advertisement processing. A specially crafted IPv6 Router Advertisement containing a zero-length Neighbor Discovery option can bypass validation during packet storage and later be reparsed without adequate validation, causing the parser ...
