Impact
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix UAF in bpf_trampoline_multi_attach_free on update failure When bpf_trampoline_update() fails before modify_fentry_multi()/ unregister_fentry_multi() is called, cur_image is unchanged (cur_image == old_image) and ftrace still calls into it. Freeing old_image in that case causes a UAF. Only free old_image when it differs from cur_image.
