CVE-2026-48863

A flaw was found in libsolv. A stack-based buffer overflow vulnerability exists in the PGP verification component due to incorrect length handling when copying EdDSA 's' MPI into a stack buffer. A remote attacker could craft a malicious Ed25519 PGP signature with mismatched MPI lengths. Processing this crafted signature could lead to a denial of service in automated package or repository processing workflows.
