Description

CVE-2026-98382 is a high-severity vulnerability in the Linux kernel affecting BPF programs bound to network devices. The flaw allows programs bound to one device to be incorrectly applied to another device, leading to out-of-bounds memory reads and kernel crashes (general protection faults and kernel panics). This occurs due to improper handling of device-bound BPF programs and offload device matching. The issue has been fixed in specific Linux kernel commits.
