CVE-2026-42393

The comparison used for the doveadm password and API key is not fully timing safe and can reveal the length of the configured secret. An attacker with access to the same network as the doveadm service, able to make repeated requests and measure response timing accurately, can learn the length of...

CVE-2026-59276

Several components in Spring Security compare security-sensitive values using standard string equality String.equals rather than a constant-time comparison. Because String.equals returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the...

Unity Linux 20.1050a Security Update: kernel (UTSA-2026-098787)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-098787 advisory. 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...

EUVD-2026-65214

The getgrav/grav-plugin-login Composer plugin before 3.9.1 used by Grav compares password reset and account activation tokens using a non-constant-time === string comparison instead of hashequals in classes/Controller.php taskReset and login.php activation handler. Because the token-submission...

pam security update

1.6.1-9.1 - pamuserdb: fix password comparison timing leak. Resolves: CVE-2026-54411 and RHEL-191704...

CVE-2026-53525

A flaw was found in WeeChat, a free chat client. The relay authentication mechanism uses a non-constant-time comparison when verifying password hashes. This vulnerability allows a remote attacker to exploit subtle timing differences during the authentication process. By analyzing these timing...

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

In Trusted Firmware Mbed TLS 2.24.0, a side-channel vulnerability exists in the decoding of Base64 PEM files. This vulnerability allows system-level administrator attackers to obtain information about secret RSA keys through a controlled-channel and side-channel attack on software running in...

Astra Linux – Vulnerability in Linux

In kernel/bpf/verifier.c in the Linux kernel before version 5.12.13, a branch prediction can be mispredicted e.g., due to type confusion, allowing a non-privileged BPF program to access arbitrary memory locations through a side-channel attack, known as CID-9183671af6db...

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 wpa

Implementations of EAP-pwd in hostapd before version 2.10 and wpasupplicant before version 2.10 are vulnerable to side-channel attacks due to cache access patterns. NOTE: This issue exists because of an incomplete fix for CVE-2019-9495...

Astra Linux – Vulnerability in wpa

Implementations of SAE in hostapd before version 2.10, and wpasupplicant before version 2.10, are vulnerable to side-channel attacks due to cache access patterns. NOTE: This issue exists due to an incomplete fix for CVE-2019-9494...

Astra Linux – Vulnerability in Linux

The kernel/bpf/verifier.c file in the Linux kernel, as of version 5.12.1, performs undesirable speculative loads. This leads to the disclosure of stack contents through side-channel attacks, known as CID-801c6058d14a. The main issue is that the BPF stack area is not properly protected against...

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 nss

During RSA key generation, bignum implementations used a variant of the Binary Extended Euclidean Algorithm, which involved significant input-dependent processes. This allowed attackers to perform electromagnetic-based side-channel attacks to capture traces that could lead to the recovery of secr...

Astra Linux – Vulnerability in Chromium

Leakage of side-channel information in DevTools in Google Chrome prior to version 94.0.4606.54 allowed a remote attacker to bypass site isolation through a crafted HTML page...

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 Linux

A issue was discovered in the Linux kernel through version 5.11.x. The kernel/bpf/verifier.c file contains unwanted out-of-bounds speculation during pointer arithmetic operations, which allows for side-channel attacks that circumvent Spectre mitigations and extract sensitive information from kern...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, amd64-microcode

A side channel vulnerability in some AMD CPUs may allow an attacker to influence the prediction of the return address. This could result in speculative execution at an address controlled by the attacker, potentially leading to the disclosure of information...
