A denial-of-service vulnerability has been identified in Open5GS versions through 2.7.7, specifically within the AMF component. The issue arises in the function 'amf_nudm_sdm_handle_provisioned' in 'nudm-handler.c', where there is no proper bounds checking when copying 'defaultSingleNssais' entries from the 'Nudm_SDM' 'am-data' response into a fixed-size array. This oversight allows for memory corruption, which can lead to a crash of the AMF process. The vulnerability can be exploited remotely, and has been publicly disclosed.
