CVE-2026-12043 HIGH PATCH This Week

Client-side memory corruption in the AWS Common Runtime aws-c-http library can be triggered by a malicious HTTP/2 server that sends a crafted sequence of HEADERS frames manipulating the HPACK dynamic table size, potentially leading to arbitrary code execution in applications that use the library as an HTTP/2 client. The CVSS 4.0 score of 8.7 (High) reflects network reachability with low complexity but requires user/client interaction (initiating a connection to the attacker server). There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
