In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix CFI mismatch in task work callback
BPF subprograms use the bpf_callback_t ABI, but task work invokes the callback through a three-argument function pointer. This trips kCFI.
Store and invoke the callback as bpf_callback_t.
