gnutls: gnutls: Information disclosure via timing side-channel in PKCS#7 padding removal

A flaw was found in gnutls. The PKCS7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerability is a form of...

postgresql: PostgreSQL: Credential recovery via covert timing channel in MD5 password comparison

A flaw was found in PostgreSQL. This vulnerability, a covert timing channel, exists in the comparison of MD5-hashed passwords during authentication. A remote attacker could exploit this to recover user credentials, gaining unauthorized access to the database. This issue specifically impacts...

CVE-2026-53236

Summary: The Linux kernel patch restricts the use of SO_ATTACH_FILTER (cBPF) on TCP sockets to users with the CAP_NET_ADMIN capability, mitigating a potential side-channel where an unprivileged process could attach a filter to leak TCP sequence/ACK numbers. Affected component: Linux kernel TCP so...

EUVD-2026-39327

In the Linux kernel, the following vulnerability has been resolved: tcp: restrict SOATTACHFILTER to priv users This patch restricts the use of SOATTACHFILTER cBPF on TCP sockets to users with CAPNETADMIN capability. This blocks potential side-channel attack where an unprivileged application...

Astra Linux – Vulnerability in OpenSSL

Issue summary: A timing side-channel that could potentially allow the recovery of the private key exists in the ECDSA signature computation. Impact summary: A timing side-channel in ECDSA signature computations could allow an attacker to recover the private key. However, measuring the timing woul...

Astra Linux – Vulnerability in mbedtls

A vulnerability was discovered in Arm Mbed TLS prior to version 2.24.0. An attacker can obtain a private key for RSA or static Diffie-Hellman through a side-channel attack targeting the generation of base blinding/unblinding values...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Arm Mbed TLS before version 2.23.0. A side channel allows the recovery of an ECC private key, which is related to functions such as mbedtlsecpcheckpubpriv, mbedtlspkparsekey, mbedtlspkparsekeyfile, mbedtlsecpmul, and mbedtlsecpmulrestartable...

Astra Linux – Vulnerability in mbedtls

A vulnerability was discovered in Arm Mbed TLS before versions 2.16.6 and 2.7.x, prior to 2.7.15. An attacker who can obtain precise side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinates of the result of scalar multiplication by...

Astra Linux – Vulnerability in mbedtls

The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS from 2.19.1 onwards does not reduce the blinded scalar before computing the inverse. This allows a local attacker to recover the private key through side-channel attacks...

Astra Linux – Vulnerability in wpa
