Security researchers have identified a slew of vulnerabilities collectively dubbed Amnesia:33. The vulnerabilities affect the TCP/IP stack, which in turn impacted millions upon millions of IoT devices across the world. The number of affected devices is impossible to estimate correctly, but they seem to number in the millions. The last major set of problems discovered in the same software was dubbed Ripple20 in 2020. The only vulnerability that stands out is CVE-2020-11904 (part of Ripple20), which was discovered within the memory allocator component used by the Treck stack.”]
