CLEANSTART-2026-JP03196 Issue summary: ChaCha20-Poly1305 and AES-OCB decryption with an empty ciphertext can report success without verifying the supplied authentication tag when the operation is finalized by calling the ...

CVE-2026-75803 affects multiple packages. Issue summary: ChaCha20-Poly1305 and AES-OCB decryption with an empty ciphertext can report success without verifying the supplied authentication tag when the operation is finalized by calling the EVPCipher function. See references for individual...

openssl: AES-OCB IV Ignored on EVP_Cipher() Path

A flaw was found in OpenSSL. Applications that use the AES-OCB encryption method with a specific one-shot interface EVPCipher will have their provided Initialization Vector IV silently discarded. This leads to the same internal cryptographic value being used repeatedly, which compromises the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: ocb: don’t leave if not joined If there is no OCB state, do not ask the driver/mac80211 to leave, as that would only cause confusion. Since the chandef state can be set or cleared, this is a simple check...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Wifi: mac80211: ocb: skipping RXnosta when the interface is not joined The ieee80211ocbrxnosta function assumes a valid channel context, which is only present after the JOINOCB operation. RX operations may occur before JOINOCB is...

Astra Linux – vulnerability in OpenSSL

Issue summary: When using the low-level OCB API directly with AES-NI or other hardware-accelerated code paths, inputs whose length is not a multiple of 16 bytes may leave the final partial block unencrypted and unauthenticated.Impact summary: The last 1–15 bytes of a message may be exposed in...
