Last modified

CVE-2023-30463 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Altran picoTCP through 1.7.0 allows memory corruption (and subsequent denial of service) because of an integer overflow in pico_ipv6_alloc when processing large ICMPv6 packets. This affects installations with Ethernet support in which a packet size greater than 65495 may occur.. EPSS estimates a 0.87% chance of exploitation in the next 30 days.
