Data disclosure and tampering in Sony FeliCa IC chips manufactured in or before 2017 stems from a missing cryptographic step (CWE-325) in the chip's contactless security handling. An attacker with physical/NFC proximity to an affected card or device can read or alter data stored on the chip, undermining the confidentiality and integrity of stored credentials, balances, or identity data. No public exploit has been identified at time of analysis, and the flaw is not listed in CISA KEV; the CVSS 4.0 base score is 7.0 (High), driven entirely by high impact under a physical attack vector.
Denial of service in libssh affects clients that use automatic certificate-based public key authentication, where logic errors cause the client to loop indefinitely when configured certificates are absent or are repeatedly rejected by the SSH server. Reported by Red Hat and shipped in Red Hat Enterprise Linux 8, 9, and 10 plus Red Hat Hardened Images, the flaw lets a hostile or misconfigured server hang a connecting client and consume CPU. There is no public exploit identified at time of analysis, and EPSS is low at 0.17% (7th percentile), consistent with an availability-only, client-side bug rather than a mass-exploited issue.
