Summary
Open5GS, an open-source 5G core network software, is affected by this flaw in its SUCI de-concealment handling. An unauthenticated attacker, such as a device or network peer, can send a specially crafted subscriber identifier that causes the software to read memory beyond the intended buffer, which may crash the service or expose sensitive data.

Read the original description
Open5GS 2.6.1 through 2.8.0 contains an out-of-bounds read vulnerability in parse_scheme_output() in lib/sbi/conv.c during SUCI de-concealment due to incomplete length validation. Remote unauthenticated UEs or SBI peers can submit a crafted SUCI with a 42-byte scheme output to a UDM, triggering a heap over-read past the buffer.
