GHSA-RM3J-F69W-WQMQ golang.org/x/crypto vulnerable to infinite loop on large channel writes

When writing data larger than 4GB in a single Write call on an SSH channel, an integer overflow in the internal payload size calculation caused the write loop to spin indefinitely, sending empty packets without making progress. The size comparison now uses int64 to prevent truncation...

GHSA-W879-237Q-WC7R golang.org/x/crypto: Invoking pathological RSA/DSA parameters may cause DoS

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...

golang.org/x/crypto is vulnerable to invoking server panic during CheckHostKey/Authenticate flow

SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil...

GHSA-78MQ-XCR3-XM33 golang.org/x/crypto is vulnerable to invoking server panic during CheckHostKey/Authenticate flow

golang.org/x/crypto vulnerable to invoking bypass of certificate restrictions

When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil Permissions with PartialSuccessError...

GHSA-Q4H4-GMJ2-QVW2 golang.org/x/crypto: Invoking byte arithmetic causes underflow and panic

An incorrectly placed cast from bytes to int allowed for server-side panic in the AES-GCM packet decoder for well-crafted inputs...

GHSA-JPPX-RXG9-JMRX golang.org/x/crypto doesn't enforce invoking key constraints

The in-memory keyring returned by NewKeyring silently accepted keys with the ConfirmBeforeUse constraint but never enforced it. The key would sign without any confirmation prompt, with no indication to the caller that the constraint was not in effect. NewKeyring now returns an error when...

GHSA-9M57-25V3-79X9 golang.org/x/crypto: Invoking pathological inputs can lead to client panic

For certain crafted inputs, a 'ed25519.PrivateKey' was created by casting malformed wire bytes, leading to a panic when used...

CVE-2026-46601

The CVE refers to a panic in the golang.org/x/image webp decoder when processing a VP8 chunk whose alpha channel size does not match the canvas size. Affected component: the WebP decoder in x/image/webp. Root cause: mismatch between VP8 chunk dimensions and the canvas size triggers a panic (crash...
