Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: aead,cipher – The key buffer is zeroed after use. I.G 9.7.B for FIPS 140-3 specifies that variables temporarily holding cryptographic information should be zeroed once they are no longer needed. This is achieved by using...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: ecdh – explicitly zeroes privatekey. The privatekey is overwritten with the key parameter passed in by the caller if present, or alternatively with a newly generated private key. However, it is possible that the caller...

EUVD-2026-49931

nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network. Prior to version 0.3.7, internal/pki/resolver.go:36-64 constructs a CAManager with the plaintext ed25519.PrivateKey after unwrapping via the master key; internal/pki/ca.go:13-16 stores it. Callers at...

nebula-mesh: Decrypted CA private key persists in heap after signing

internal/pki/resolver.go:36-64 constructs a CAManager with the plaintext ed25519.PrivateKey after unwrapping via the master key; internal/pki/ca.go:13-16 stores it. Callers at internal/api/enroll.go:116, internal/api/updates.go:297, and internal/api/mobilebundle.go:40 use the manager for one Sign...

PT-2026-48603

Name of the Vulnerable Software and Affected Versions nebula-mesh versions prior to 0.3.7 Description Decrypted CA private keys persist in the process heap because the CAManager does not zeroise the plaintext ed25519.PrivateKey after use. This occurs when callers at internal/api/enroll.go:116,...

CVE-2026-43336

A flaw was found in the Linux kernel's ChaCha cryptographic algorithm implementation. The permutedstate local variable, which is sufficient to compute the original cryptographic key, was not properly zeroized before leaving its scope. This oversight could allow an attacker to recover the...

SUSE CVE-2026-43336

In the Linux kernel, the following vulnerability has been resolved: lib/crypto: chacha: Zeroize permutedstate before it leaves scope Since the ChaCha permutation is invertible, the local variable 'permutedstate' is sufficient to compute the original 'state', and thus the key, even after the...

CVE-2026-43336

CVE-2026-43336 – linux kernel ChaCha secret handling : The vulnerability arises in lib/crypto: chacha where the permuted_state is not zeroized before leaving scope, allowing the original state (and thus the key) to be inferred after the permutation. The documented fix is to explicitly zeroize per...
