CVE-2026-0128

CVE-2026-0128 affects code in RtcpFbPacket::decodeRtcpFbPacket, where an integer overflow can trigger an out-of-bounds read. This could lead to remote information disclosure without extra privileges. Exploitation requires user interaction. The connected documents consistently describe the same is...

kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result

A flaw was found in the Linux kernel's Wi-Fi mac80211 subsystem. The ieee80211invokefastrx function uses a static variable for rxresult, which is shared across concurrent calls. This can lead to incorrect processing of Wi-Fi packets, where a packet might be mishandled or its status incorrectly...

gnutls: gnutls: Denial of Service via DTLS packet reordering vulnerability

A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security DTLS packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This...

CVE-2026-10638

subsys/net/ip/icmpv6.c reads the network interface from a netpkt after that packet has been handed to nettrysenddata. In icmpv6handleechorequest and neticmpv6senderror, the post-send statistics update calls netpktifacereply/netpktifacepkt on the just-sent packet. The send path nettrysenddata -...

CVE-2026-10637

subsys/net/ip/ipv6mld.c:mldsend read the packet interface via netpktifacepkt after netsenddatapkt returned successfully. Per the network stack's ownership contract include/zephyr/net/netcore.h, and the explicit warning in subsys/net/ip/netcore.c:453-460 'do not use pkt after that call', a...

CVE-2026-10640 Use-after-free reading `net_pkt` `iface` after send in IPv6 Neighbor Discovery (`ipv6_nbr.c`)

Zephyr's IPv6 Neighbor Discovery send paths netipv6sendna, netipv6sendns, netipv6sendrs in subsys/net/ip/ipv6nbr.c updated the per-interface ICMP-sent statistics by calling netpktifacepkt after netsenddatapkt had already returned successfully. On the success path the network stack owns and releas...

CVE-2026-10639

Summary: Zephyr’s native IPv4 icmpv4_handle_echo_request() can perform a use-after-free when updating per-interface statistics after sending an ICMP echo reply. The code hands the echo-reply to the TX path, which may drop the packet and free the net_pkt before the post-send stats update runs. As ...

CVE-2026-10639 Use-after-free reading `net_pkt_iface()` of a sent ICMPv4 echo-reply packet in `icmpv4_handle_echo_request()`

In Zephyr's native IPv4 stack, icmpv4handleechorequest in subsys/net/ip/icmpv4.c builds an echo-reply packet reply, hands it to nettrysenddata, and then, on success, calls netstatsupdateicmpsentnetpktifacereply. nettrysenddata transfers ownership of reply to the TX path netiftryqueuetx - netiftx ...

CVE-2026-10637

CVE-2026-10637 describes a use-after-free in Zephyr’s IPv6 MLD path: after net_send_data(pkt) returns, the code reads net_pkt_iface(pkt) from a freed net_pkt, risking NULL or stale pointers and potential crash or memory corruption. The root cause is violating the network stack ownership contract;...

In Zephyr's IPv4 IGMP implementation, igmpsend in subsys/net/ip/igmp.c read the network interface back out of the packet via netpktifacepkt after the packet had been handed to netsenddata. On the successful-send path the packet's last reference may already have been released by the L2 driver or b...
