CVE-2026-13758

CryptX versions before 0.088001 for Perl compare AEAD authentication tags in non-constant time in the streaming decryptdone path. The decryptdone$tag form compares it against the computed tag with memNE memcmp != 0, which short-circuits on the first differing byte, so its run time depends on the...

CVE-2026-6458

Missing cryptographic step in Caliptra Core Firmware aes256gcmupdate module results in an incorrect GCM authentication tag. When the streaming AES-256-GCM API is used with empty AAD, the hardware GHASH accumulator state is not saved after the first update call, causing the final tag to exclude th...

CVE-2026-6458

CVE-2026-6458 involves the Caliptra Core Firmware (aes_256_gcm_update module) where a missing cryptographic step in the streaming AES-256-GCM API with empty AAD leads to the hardware GHASH accumulator state not being saved after the first update. As a result, the final GCM authentication tag does...

CVE-2026-57062

CMS Cryptographic Message Syntax parsing in gpgsm in GnuPG through 2.5.20 mishandles the CMS format for AES-GCM because aes-ICVlen is supposed to be 12 bytes but 4 bytes is accepted. NOTE: this is related to CVE-2026-34182...

SUSE CVE-2026-43994

Coturn is a free open source implementation of TURN and STUN Server. Versions prior to 4.10.0 contain a stack buffer overflow in decodeoauthtokengcm. A uint16t noncelen field read from an attacker-supplied OAuth access token 0-65535 is passed directly to memcpy as the copy length into a 256-byte...

Astra Linux – Vulnerability in Linux, Linux 5.10

A memory leak flaw was discovered in the Linux kernel’s ccprunaesgcmcmd function, which allows an attacker to cause a denial of service. This vulnerability is similar to the older CVE-2019-18808. The greatest threat posed by this vulnerability is to system availability...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: crypto: afalg – Fixed an issue where initialisation was missing, affecting gcm-aes-s390. Fixed the afalgallocareq function to initialize areq-firstrsgl.sgl.sgt.sgl to point to the scatterlist array in areq-firstrsgl.sgl.sgl...

Astra Linux – Vulnerability in mbedtls

Mbed TLS before version 3.6.4 has a race condition in AESNI detection when certain compiler optimizations are applied. An attacker may be able to extract an AES key from a multithreaded program, or perform a GCM forgery...

CVE-2026-43994

CVE-2026-43994 affects coturn before 4.10.0: a stack buffer overflow in decode_oauth_token_gcm() occurs when parsing an attacker-supplied OAuth token’s nonce_len, which is copied directly to a 256-byte stack buffer without bounds checking. Up to 735 bytes of attacker-controlled data may be writte...
