The vulnerability of the nft_inner_parse_l2l3() function in the net/netfilter/nft_inner.c module of the Linux operating system allows a malicious actor to gain unauthorized access to protected information or cause service failures.

The vulnerability of the nftinnerparsel2l3 function in the net/netfilter/nftinner.c module of the Linux operating system is related to the use of pointer offsets that are outside their range when processing IPv6 packets. Exploiting this vulnerability can allow an attacker to gain unauthorized...

CVE-2026-53228

A flaw was found in the Linux kernel's Simple Internet Transition SIT tunnel driver for IPv6. When processing network traffic with Generic Segmentation Offload GSO enabled, the driver may use a stale pointer to the inner IPv6 header after the socket buffer skb head has been reallocated. This can...

kernel: tcp: fix potential race in tcp_v6_syn_recv_sock()

A flaw was found in the Linux kernel. A race condition exists in the TCP Transmission Control Protocol IPv6 Internet Protocol version 6 socket handling, specifically within the tcpv6synrecvsock function. This occurs because a child socket becomes visible in the TCP hash table before its...

kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

CVE-2026-53006

A flaw was found in the Linux kernel's IPv6 Internet Protocol version 6 implementation. This vulnerability, a Use-After-Free UAF error, occurs due to incorrect caching of network packet addresses before a memory operation. An attacker could potentially exploit this flaw to cause memory corruption...

CANBoat through 6.22, fixed in commit a5a22b7, contains an off-by-one global buffer overflow in the searchForPgn function in analyzer/pgn.c that allows remote attackers to crash the application. Attackers can deliver a crafted NMEA-2000 message with an out-of-range PGN value over CAN bus or...

CVE-2026-13351 net: Maliciously fragmented IPv6 packets can prevent receiving/processing future incoming packets

Zephyr's IPv6 network stack can be prevented from receiving or processing future incoming packets by sending a small number of maliciously fragmented IPv6 packets. When such a packet is handled by the fragment-header processing path, the associated RX network packet buffer allocated from a memory...

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...
