CVE-2026-80793

In the Linux kernel, the following vulnerability has been resolved: ipv4: reject undersized MTUs in ipdofragment ipdofragment subtracts the IPv4 header length from the effective MTU and passes the resulting payload MTU to ipfragnext. If the effective MTU is smaller than hlen + 8, ipfragnext round...

CVE-2026-80793

This Linux kernel vulnerability affects the IPv4 fragmentation path in ip_do_fragment() . When the effective MTU is smaller than the IPv4 header length plus 8, the function passes a zero-length payload to ip_frag_next() , causing the fragmentation state to stall indefinitely. The result is a soft...

kernel: ipv4: free net->ipv4.sysctl_local_reserved_ports after unregister_net_sysctl_table()

A flaw was found in the Linux kernel's IPv4 networking component. The ipv4sysctlexitnet function prematurely frees the net-ipv4.sysctllocalreservedports memory. This can lead to a use-after-free vulnerability, where other threads might attempt to access deallocated memory. Such an issue can resul...

The vulnerability of the `udp_read_skb()` function in the `net/ipv4/udp.c` module of the Linux operating system’s kernel-based IPv4 protocol implementation allows a attacker to cause a service failure.

The vulnerability of the udpreadskb function in the net/ipv4/udp.c module of the Linux kernel’s IPv4 protocol implementation is related to the lack of resource initialization. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...

The vulnerability of the replace_nexthop_single() function in the net/ipv4/nexthop.c module of the Linux operating system’s IPv4 kernel implementation allows a attacker to cause a service failure.

The vulnerability of the replacenexthopsingle function in the net/ipv4/nexthop.c module of the Linux operating system’s IPv4 protocol implementation is related to the swapping of pointers. Exploiting this vulnerability could allow an attacker to cause a service failure...

ip-address: ip-address: Server-Side Request Forgery via IPv4-mapped/NAT64 IPv6 address misclassification

A flaw was found in the ip-address library. This library, used for parsing and manipulating IPv4 and IPv6 addresses in JavaScript, is vulnerable to Server-Side Request Forgery SSRF due to incorrect classification of IPv4-mapped/NAT64 IPv6 addresses. An attacker could exploit this misclassificatio...

ip-address: ip-address: Inconsistent IP address parsing leads to Server-Side Request Forgery (SSRF) and trust-boundary bypass

A flaw was found in the ip-address library. This library incorrectly interprets IPv4 address octets with leading zeros as decimal, while standard network parsers interpret them as octal. This inconsistency can cause applications to misclassify network targets, allowing a remote attacker to bypass...
