SUSE CVE-2026-41565

CryptX versions before 0.088001 for Perl have a stack buffer overflow in four AEAD decryptverify helpers. The gcmdecryptverify, ccmdecryptverify, chacha20poly1305decryptverify and eaxdecryptverify XS routines copied the caller-supplied authentication tag into a fixed 144-byte stack buffer...

CVE-2026-41565

A flaw was found in perl-CryptX. A stack buffer overflow vulnerability exists in the AEAD Authenticated Encryption with Associated Data decryptverify helper routines. An attacker who can control the length of the authentication tag provided to these routines can cause a buffer overflow, potential...

EUVD-2026-32414

In the Linux kernel, the following vulnerability has been resolved: crypto: authencesn - reject short ahash digests during instance creation authencesn requires either a zero authsize or an authsize of at least 4 bytes because the ESN encrypt/decrypt paths always move 4 bytes of high-order sequen...

Astra Linux – Vulnerability in Linux 5.15

A issue was discovered in the Linux kernel before version 6.3.4. ksmbd has a buffer overflow vulnerability in the smb2findcontextvals function, when the namelen of createcontext is larger than the length of the tag...

Astra Linux – Vulnerability in nss

A flaw was discovered in the implementation of CHACHA20-POLY1305 in NSS versions prior to 3.55. When using multi-part Chacha20, it could lead to out-of-bounds reads. This issue was addressed by explicitly disabling multi-part ChaCha20 which was not functioning correctly and enforcing strict tag...

libcrux: Potential Panic on Overlong Ciphertext Buffer

An application that passes in a ciphertext buffer of length greater than ptxt.len + TAGLEN to libcruxchacha20poly1305::encrypt or libcruxchacha20poly1305::xchacha20poly1305::encrypt would experience a panic. Impact An application where the length of the ciphertext buffer is under attacker control...

Unity Linux 20.1060e / 20.1070e Security Update: nss (UTSA-2026-017618)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-017618 advisory. A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS in versions before 3.55. When using multi-part Chacha20, it could cause out-of-bounds reads. Thi...

CVE-2026-43077

CVE-2026-43077 concerns the Linux kernel crypto/algif_aead path. The vuln arises from a miscalculation of the minimum receive buffer size during decryption because the tag size was not considered in the size check. The fix adds the required extra length to account for the authentication tag, prev...
