CVE-2026-7424

Integer underflow in the DHCPv6 sub-option parser in FreeRTOS-Plus-TCP before V4.4.1 and V4.2.6 allows an adjacent network actor to corrupt the device's IPv6 address assignment, DNS configuration, and lease times, and to cause a denial of service permanent IP task freeze requiring hardware reset ...

CVE-2026-7426 Out-of-Bounds Write via Unsanitized Prefix Length in Router Advertisement Processing in FreeRTOS-Plus-TCP

Insufficient validation of the prefix length field in IPv6 Router Advertisement processing in FreeRTOS-Plus-TCP before V4.2.6 and V4.4.1 allows an adjacent network actor to cause memory corruption by sending a crafted Router Advertisement with a prefix length value exceeding the maximum valid...

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-2026-7424 Integer Underflow in DHCPv6 Sub-Option Parser in FreeRTOS-Plus-TCP

Integer underflow in the DHCPv6 sub-option parser in FreeRTOS-Plus-TCP before V4.4.1 and V4.2.6 allows an adjacent network actor to corrupt the device's IPv6 address assignment, DNS configuration, and lease times, and to cause a denial of service permanent IP task freeze requiring hardware reset ...

EUVD-2026-26277

Integer underflow in the DHCPv6 sub-option parser in FreeRTOS-Plus-TCP before V4.4.1 and V4.2.6 allows an adjacent network actor to corrupt the device's IPv6 address assignment, DNS configuration, and lease times, and to cause a denial of service permanent IP task freeze requiring hardware reset ...

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-2026-7422 MAC Address Validation Bypass in FreeRTOS-Plus-TCP IPv4 and IPv6 Packet Processing

Insufficient packet validation in FreeRTOS-Plus-TCP before V4.2.6 and V4.4.1 allows an adjacent network actor to bypass all checksum and minimum-size validation by spoofing the Ethernet source MAC address to match one of the device's own registered endpoints, because the loopback detection...

net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

ovn: OVN: Information disclosure via crafted DHCPv6 packets

A flaw was found in OVN Open Virtual Network. A remote attacker, by sending crafted DHCPv6 Dynamic Host Configuration Protocol for IPv6 SOLICIT packets with an inflated Client ID length, could cause the ovn-controller to read beyond the bounds of a packet. This out-of-bounds read can lead to the...
