发布于3月6日3月6日 Members Amazon Linux AMI 2: CVE-2024-38662: Security patch for kernel (Multiple Advisories) Severity 4 CVSS (AV:L/AC:M/Au:S/C:N/I:C/A:N) Published 06/21/2024 Created 08/14/2024 Added 08/14/2024 Modified 01/30/2025 Description 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.
