Detailed vulnerability description
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the bpf_attach_type_to_tramp(), __bpf_trampoline_link_prog(), __bpf_trampoline_unlink_prog(), bpf_shim_tramp_link_release() and bpf_trampoline_link_cgroup_shim() functions in kernel/bpf/trampoline.c, within the bpf_tracing_link_release() and bpf_tracing_prog_attach() functions in kernel/bpf/syscall.c, within the bpf_prog_alloc_no_stats() function in kernel/bpf/core.c, within the prog_fd_array_get_ptr() function in kernel/bpf/arraymap.c. A local user can perform a denial of service (DoS) attack.
