CVE-2026-110353

HAProxy versions 3.2 before 3.4.6 are vulnerable to a denial of service (worker-thread CPU exhaustion) due to a flaw in the h2c_handle_ping function within src/mux_h2.c. The root cause is a failure to check for a short read during the processing of truncated HTTP/2 PING frames . This causes the H...
