No known exploits are reported in the wild, and no official patch information is provided in the source data.
AI Analysis
Technical Summary
The mirage-crypto-pk package for OCaml versions before 2.3.0 contains a vulnerability where an undocumented exception occurs when processing small messages during RSA encryption or decryption operations. This exception could lead to denial of service conditions but does not affect confidentiality or integrity of the cryptographic operations. The CVSS 3.1 score is 4.3 (medium), reflecting network attack vector, low complexity, requiring low privileges, no user interaction, and only availability impact. There is no vendor advisory or patch information available in the provided data.
Potential Impact
The vulnerability may cause availability issues by triggering an undocumented exception during RSA encryption or decryption of small messages. There is no impact on confidentiality or integrity. No known exploitation in the wild has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should be cautious when processing small messages with RSA operations in affected versions.
