Technical details
The ogs_pfcp_parse_volume_measurement() function in lib/pfcp/types.c fails to validate the length of Volume Measurement Information Elements, allowing an attacker to read up to 48 bytes past the allocated buffer. An unauthenticated remote attacker can send a crafted PFCP Session Report Request to UDP port 8805, triggering the heap out-of-bounds read and potentially causing denial of service or information disclosure.
