CVE ID :CVE-2026-31890<\/p>\n

Description :Inspektor Gadget is a set of tools and framework for data collection and system inspection on Kubernetes clusters and Linux hosts using eBPF. Prior to 0.50.1, in a situation where the ring-buffer of a gadget is \u2013 incidentally or maliciously \u2013 already full, the gadget will silently drop events. The include\/gadget\/buffer.h file contains definitions for the Buffer API that gadgets can use to, among the other things, transfer data from eBPF programs to userspace. For hosts running a modern enough Linux kernel (>= 5.8), this transfer mechanism is based on ring-buffers. The size of the ring-buffer for the gadgets is hard-coded to 256KB. When a gadget_reserve_buf fails because of insufficient space, the gadget silently cleans up without producing an alert. The lost count reported by the eBPF operator, when using ring-buffers \u2013 the modern choice \u2013 is hardcoded to zero. The vulnerability can be used by a malicious event source (e.g. a compromised container) to cause a Denial Of Service, forcing the system to drop events coming from other containers (or the same container). This vulnerability is fixed in 0.50.1.<\/p>\n
