CVE-2026-52972

CVE-2026-52972 affects the Linux kernel crypto/af_alg component, causing an arithmetic overflow when handling associated data lengths during the TX buffer size check. The root cause is the potential overflow if AD length is not capped; the fix caps the AD length to 0x80000000. Multiple OS vendors...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: BPF: crypto: Use the correct destructor kfunc type With CONFIGCFI enabled, the kernel strictly ensures that indirect function calls use a function pointer type that matches the target function. I encountered the following type...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the virtio-crypto device of QEMU. A malicious guest operating system can exploit a missing length limit in the AKCIPHER path, resulting in uncontrolled memory allocation. This can lead to a denial of service attack on the host system, causing the QEMU process to terminate...

In the Linux kernel, the following vulnerability has been resolved: crypto: afalg – Zero initialize memory allocated via sockkmalloc Several crypto user API contexts and requests that were allocated using sockkmalloc remained uninitialized. This meant that callers had to explicitly set the fields...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: crypto: seqiv - Do not use req-iv after cryptoaeadencrypt As soon as cryptoaeadencrypt is called, the underlying request may be freed by an asynchronous completion. Therefore, dereferencing req-iv after its return is invalid...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...
