| 标题 | Open5GS SGWC v2.7.6 Denial of Service |
|---|
| 描述 | SGW-C can be forced to abort (core dump) due to an ogs_assert in the PFCP path when processing a crafted GTPv2-C session setup flow. The crash is triggered after SGW-C enters session context, then hits an error path (No GTP TEID) and finally aborts on: Assert: ogs_pfcp_build_update_far_activate: Assertion 'far->apply_action & OGS_PFCP_APPLY_ACTION_FORW' failed Location: ../lib/pfcp/build.c:647, which results in DoS. |
