CVE-2024-38662

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

bpf: Allow delete from sockmap/sockhash only if update is allowed

We have seen an influx of syzkaller reports where a BPF program attached to
a tracepoint triggers a locking rule violation by performing a map_delete
on a sockmap/sockhash.

We don't intend to support this artificial use scenario. Extend the
existing verifier allowed-program-type check for updating sockmap/sockhash
to also cover deleting from a map.

>From now on only BPF programs which were previously allowed to update
sockmap/sockhash can delete from these map types.

The Linux kernel CVE team has assigned CVE-2024-38662 to this issue.
