Denial Of Service (DoS)CVE-2026-39829 Published Jun 2, 2026
75
High Risk

TL;DR
The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public key authentication. RSA moduli are now limited to 8192 bits, and DSA parameters are validated per FIPS 186-2.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and if you use the golang.org/x/crypto/ssh functionalities.
Background info
golang.org/x/crypto is vulnerable to Denial Of Service (DoS) in versions 0.0.0 - 0.51.0.
How to fix this
Upgrade the golang.org/x/crypto library to the patch version.
