Description
A flaw was found in the Linux kernel's Berkeley Packet Filter (BPF) component. This vulnerability involves a reference count leak within the bpf_prog_test_run_xdp() function, specifically when an error handling path fails to call a necessary buffer conversion function. A local user could exploit this to cause a resource leak, preventing network devices from being properly released. This could ultimately lead to a Denial of Service (DoS) condition.
