golang.org/x/crypto/ssh: golang.org/x/crypto/ssh: Denial of Service via crafted AES-GCM packet decoder inputs

A flaw was found in golang.org/x/crypto/ssh. A remote attacker could send specially crafted inputs to the AES-GCM packet decoder. This could lead to an incorrectly placed cast from bytes to an integer, causing a server-side panic and resulting in a Denial of Service DoS for the affected system...

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...

CVE-2026-87732

An issue was discovered in the mirage-crypto package before 2.2.0 for OCaml. The AES.GCM.authenticatedecryptinto and Chacha20.authenticatedecryptinto functions write the decrypted plaintext into a caller-provided buffer and only then compares the tag. On a forged tag, the functions returns false,...
