The attacker also chooses the freed allocation size via `cnt` and triggers the dangling consumer at will by exec'ing their own uprobe'd binary.\nPR:L - Loading the `BPF_PROG_TYPE_KPROBE` program requires `CAP_BPF`+`CAP_PERFMON`, which is a restricted tracing capability set rather than full administrative control, and it is routinely delegated to unprivileged contexts via BPF tokens (bpffs `delegate_cmds`/`delegate_progs`) or granted to non-root observability/container workloads.

That is full disclosure of kernel memory.\nI:H - The dangling `uc->handler(uc, regs)` call in `handler_chain()` and the `prog->bpf_func()` dispatch reached through the freed `uprobe->link` give control-flow hijack from an attacker-sized, attacker-timed heap object, which is a standard route to arbitrary kernel write and privilege escalation.\nA:H - Even without exploitation, walking the freed consumer list on the next breakpoint hit dereferences poisoned or reused slab memory, producing a KASAN slab-use-after-free and a kernel oops/panic \u2014 exactly what syzbot reported.
