RIOT is an open-source microcontroller operating system, designed to match the requirements of Internet of Things (IoT) devices and other embedded devices. A vulnerability was discovered in the IPv6 fragmentation reassembly implementation of RIOT OS v2025.07. When receiving an fragmented IPv6 packet with fragment offset 0 and an empty payload, the payload pointer is set to NULL. However, the implementation still tries to copy the payload into the reassembly buffer, resulting in a NULL pointer dereference which crashes the OS (DoS). To trigger the vulnerability, the `gnrc_ipv6_ext_frag` module must be enabled and the attacker must be able to send arbitrary IPv6 packets to the victim. RIOT OS v2025.10 fixes the issue.

A denial-of-service vulnerability exists in the omec-project UPF (component upf-epc/pfcpiface) up to at least version upf-epc-pfcpiface:2.1.3-dev. When the UPF receives a PFCP Association Setup Request that is missing the mandatory NodeID Information Element, the association setup handler dereferences a nil pointer instead of validating the message, causing a panic and terminating the UPF process. An attacker who can send PFCP Association Setup Request messages to the UPF's N4/PFCP endpoint can exploit this issue to repeatedly crash the UPF and disrupt user-plane services.

A denial-of-service vulnerability exists in the omec-project UPF (pfcpiface component) in version upf-epc-pfcpiface:2.1.3-dev. When the UPF receives a PFCP Session Report Response that is missing the mandatory Cause Information Element, the session report handler dereferences a nil pointer instead of rejecting the malformed message. This triggers a panic and terminates the UPF process. An attacker who can send PFCP Session Report Response messages to the UPF's N4/PFCP endpoint can exploit this flaw to repeatedly crash the UPF and disrupt user-plane services.

A denial-of-service vulnerability exists in the omec-project UPF (pfcpiface component) in version upf-epc-pfcpiface:2.1.3-dev. After PFCP association is established, a PFCP Session Establishment Request that is missing the mandatory F-SEID (CPF-SEID) Information Element is not properly validated. The session establishment handler calls IE.FSEID() on a nil pointer, which triggers a panic and terminates the UPF process. An attacker who can send PFCP Session Establishment Request messages to the UPF's N4/PFCP endpoint can exploit this issue to repeatedly crash the UPF and disrupt user-plane services.

Alloy Core libraries at the root of the Rust Ethereum ecosystem. Prior to 0.8.26 and 1.4.1, an uncaught panic triggered by malformed input to alloy_dyn_abi::TypedData could lead to a denial-of-service (DoS) via eip712_signing_hash(). Software with high availability requirements such as network services may be particularly impacted. If in use, external auto-restarting mechanisms can partially mitigate the availability issues unless repeated attacks are possible. The vulnerability was patched by adding a check to ensure the element is not empty before accessing its first element; an error is returned if it is empty. The fix is included in version v1.4.1 and backported to v0.8.26.
