Description

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.
