{"cve":"CVE-2026-44778","nvd":{"published":"2026-09-15T17:17:14.970","modified":"2026-09-30T17:43:24.057","status":"Awaiting Analysis","description":"Inspektor Gadget is a set of tools and framework for data collection and system inspection on Kubernetes clusters and Linux hosts using eBPF. From 0.28.0 until 0.53.1, the USDT note parser in pkg/uprobetracer/usdt.go can allow an unprivileged container to crash or exhaust the memory of the privileged Inspektor Gadget process when a custom gadget containing a SEC(\"usdt/...\") eBPF section attaches to a crafted ELF binary. The getUsdtInfo() function reads the .note.stapsdt section without validating that DescSize is large enough for three address fields, allowing an out-of-bounds slice operation to panic, and it uses untrusted NameSize and DescSize values for allocations that can consume gigabytes of memory. The parser also invokes debug/elf without panic recovery, allowing other malformed ELF structures to terminate the process. No gadget shipped by Inspektor Gadget uses USDT probes, so only deployments using custom USDT gadgets are affected, and the demonstrated impact is denial of service rather than code execution or privilege escalation. This issue is fixed in version 0.53.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","score":2.9},"cvss_v3":null,"cwes":["CWE-20"],"references":["https://github.com/inspektor-gadget/inspektor-gadget/commit/27263e50d6287891eee4d9a1cfae62681260e1a2","https://github.com/inspektor-gadget/inspektor-gadget/commit/aaffacc6a9e43b4de5ce8f8148e6c2d9a1ea6026","https://github.com/inspektor-gadget/inspektor-gadget/pull/5547","https://github.com/inspektor-gadget/inspektor-gadget/releases/tag/v0.53.1","https://github.com/inspektor-gadget/inspektor-gadget/security/advisories/GHSA-7cfq-5mhv-jrp9"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-44778","score":0.0063,"percentile":0.49872,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-7cfq-5mhv-jrp9","url":"https://osv.dev/vulnerability/GHSA-7cfq-5mhv-jrp9","summary":"Inspektor Gadget: Unprivileged container can crash USDT note parser via crafted ELF (no shipped gadget affected)","modified":"2026-06-25T19:56:30.592870861Z","packages":[{"ecosystem":"Go","name":"github.com/inspektor-gadget/inspektor-gadget","purl":"pkg:golang/github.com/inspektor-gadget/inspektor-gadget","ranges":[">=0.28.0 <0.53.1"],"fixed":["0.53.1"]}]},{"id":"GO-2026-5214","url":"https://osv.dev/vulnerability/GO-2026-5214","summary":"Inspektor Gadget: Unprivileged container can crash USDT note parser via crafted ELF (no shipped gadget affected) in github.com/inspektor-gadget/inspektor-gadget","modified":"2026-06-25T19:45:15.318252987Z","packages":[{"ecosystem":"Go","name":"github.com/inspektor-gadget/inspektor-gadget","purl":"pkg:golang/github.com/inspektor-gadget/inspektor-gadget","ranges":[">=0.28.0 <0.53.1"],"fixed":["0.53.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
