CVE-2024-38373

CVE-2024-38373 affects FreeRTOS-Plus-TCP, specifically versions 4.0.0 through 4.1.0. The issue is a buffer over-read in the DNS Response Parser when processing domain names in a DNS response, which can allow reading beyond the DNS response buffer if a crafted response uses a domain name length va...

CVE-2025-11616

CVE-2025-11616 affects FreeRTOS-Plus-TCP: a missing validation check in the ICMPv6 packet processing code can cause an out-of-bounds read when handling certain ICMPv6 message types smaller than expected. The issue applies to IPv6-enabled applications. The documented mitigation is to upgrade to th...

CVE-2026-7425

The CVE-2026-7425 issue affects FreeRTOS-Plus-TCP’s IPv6 Router Advertisement parser. In versions prior to V4.2.6 and V4.4.1, insufficient option length validation allows a crafted Router Advertisement with a truncated PREFIX_INFORMATION option to cause a device crash (DoS). The vulnerability is ...

CVE-2026-7424

CVE-2026-7424 describes an integer underflow in the DHCPv6 sub-option parser of FreeRTOS-Plus-TCP. The issue affects FreeRTOS-Plus-TCP versions before V4.4.1 and before V4.2.6, and is triggered when DHCPv6 is enabled. An adjacent network actor can exploit the underflow by sending a crafted DHCPv6...

CVE-2026-7426

The CVE-2026-7426 entry concerns the IPv6 Router Advertisement handling in FreeRTOS-Plus-TCP. Insufficient validation of the prefix length field in Router Advertisement processing allows memory corruption (heap buffer overflow) on the affected stack when processing RA messages. Affected versions ...

CVE-2026-7423

The CVE affects FreeRTOS-Plus-TCP: an integer underflow in ICMP/ICMPv6 echo reply handling prior to V4.4.1 and V4.2.6. Subtracting header sizes from a packet length without validating size enables a heap out-of-bounds read (~65KB), allowing an adjacent attacker to cause a device crash (DoS) when ...

CVE-2026-7422

CVE-2026-7422 affects FreeRTOS-Plus-TCP; insufficient packet validation in IPv4/IPv6 processing (before V4.2.6 and V4.4.1) allows an adjacent attacker to bypass checksum and minimum-size checks by spoofing the Ethernet source MAC to a local endpoint, since loopback-detection skips validation for ...

CVE-2025-11617

CVE-2025-11617 describes a missing validation check in FreeRTOS-Plus-TCP’s IPv6 packet processing that can cause an out-of-bounds read when handling IPv6 packets with incorrect payload lengths. Affected component is the IPv6 processing path in FreeRTOS-Plus-TCP; issue is limited to IPv6-enabled a...

CVE-2025-11618

CVE-2025-11618 affects FreeRTOS-Plus-TCP’s UDP/IPv6 packet processing. The vulnerability is a missing validation check that can cause an invalid pointer dereference when a UDP/IPv6 packet carries an incorrect IP version field within IPv6 traffic. Impact is limited to IPv6-enabled applications; no...
