CVE-2026-46595

CVE-2026-46595 affects golang.org/x/crypto/ssh. The issue arises when VerifiedPublicKeyCallback is invoked with a callback type other than public key, causing the source-address validation to be bypassed and enabling an authorization bypass. The description notes this is a continuation of CVE-202...

CVE-2026-42508

CVE-2026-42508 concerns revocation checks for a CA SignatureKey. The fix adds revocation checks for both the CA 'key' and 'key.SignatureKey' (prevents bypass). The CVE is rated CRITICAL (CVSS 3.1: 9.1, Network, no user interaction). Exploitation details are not provided in the documents; mitigati...

CVE-2026-39831

CVE-2026-39831 involves the Verify() method for FIDO/U2F security key types ([email protected], [email protected]) where the User Presence flag was not checked. This allowed signatures generated without physical user interaction to be accepted, enabling unattended use of...

CVE-2026-39834

CVE-2026-39834 concerns a flaw in golang.org/x/crypto/ssh where writing data larger than 4GB in a single Write on an SSH channel triggers an integer overflow in the internal payload size calculation. The overflow causes the write loop to spin indefinitely, sending empty packets and making no prog...

CVE-2026-39830

CVE-2026-39830 describes a vulnerability in golang.org/x/crypto/ssh where a malicious SSH peer can send unsolicited global request responses to fill an internal buffer, causing the connection read loop to block. The blocked goroutine cannot be released by Close(), leading to a per-connection reso...

CVE-2026-39827

The CVE-2026-39827 issue (an authenticated SSH client repeatedly opening channels that are rejected by the server) caused unbounded memory growth and server process crashes. All affected SUSE/openSUSE advisories indicate the fix is included in rclone-1.74.2-1.1 for GA media on openSUSE Tumbleweed...

CVE-2026-39829

CVE-2026-39829 affects golang.org/x/crypto/ssh. The vulnerability arises because the RSA/DSA public key parsers did not enforce size limits on key parameters, allowing crafted keys with oversized modulus or DSA parameters to cause prolonged CPU use during signature verification. Affected behavior...

CVE-2026-39833

The CVE-2026-39833 issue affects the in-memory keyring used by golang.org/x/crypto/ssh/agent. The ConfirmBeforeUse constraint was silently accepted but not enforced by NewKeyring(), allowing keys to sign without a required confirmation prompt and without notifying the caller. The patch fixes this...

CVE-2026-39832

CVE-2026-39832 concerns how remote agent constraint extensions are serialized. The issue allowed destination restrictions (e.g., [email protected]) to be stripped when forwarding keys, effectively enabling unrestricted use of the key on the remote host. The description notes th...

CVE-2026-39835

CVE-2026-39835 affects golang.org/x/crypto/ssh where CertChecker used as a public key callback could panic if IsUserAuthority or IsHostAuthority callbacks were nil during a client certificate authentication flow. The concrete fix implemented is that CertChecker now returns an error instead of pan...

CVE-2026-46597

CVE-2026-46597 describes an incorrectly placed cast from bytes to int that can cause a server-side panic in the AES-GCM packet decoder when processing crafted inputs. The entry lists high availability impact with network-based exploitability and no privileges required, but the provided documents ...

CVE-2026-39828

CVE-2026-39828 affects golang.org/x/crypto/ssh: when an SSH server authentication callback returns PartialSuccessError with non-nil Permissions, the permissions were previously discarded, potentially dropping certificate restrictions such as force-command after a second factor. Returning non-nil ...

CVE-2026-46598

CVE-2026-46598: Several connected sources confirm that for certain crafted inputs, a golang.org/x/crypto/ssh/agent workflow can cast malformed wire bytes into an ed25519.PrivateKey, causing a panic when the key is used. The description is consistent across NVD, Debian, CIRCL, and OSV entries, ind...

CVE-2025-58181
