CVE-2026-92486

Estado: RecibidaSin puntuar—

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.
