从截图中可以提取到以下关于漏洞的关键信息： Title: Open5GS SGWC v2.7.6 Denial of Service Description: SGWC can be forced to crash if a BearerResourceFailureIndication (GTPv2-C message type 69) is received after the corresponding S11 Bearer Resource procedure transaction has already timed out and been freed. The handler assumes the associated S11 transaction ( ) is always valid. When the S11-side transaction expires before the late S5-C indication arrives, becomes NULL, and this leads to a remote DoS, which can be achieved by controlling message timing.
