CVE-2026-44778 is a denial-of-service vulnerability in Inspektor Gadget's USDT note parser, specifically in ELF parsing logic used when deploying custom gadgets that use USDT probes. A crafted ELF file placed in a targeted binary or library can trigger unsafe parsing conditions, including out-of-bounds slice access and excessive memory allocation based on attacker-controlled note metadata. The vulnerable code path is in the USDT handling/parsing logic in pkg/uprobetracer/usdt.go. When the privileged Inspektor Gadget process parses the malicious ELF from an unprivileged container context, it can panic or consume enough memory to be OOM-killed.
