Exploiting Per-Core Leakage: Electromagnetic Side-Channel Monitoring of Multicore Architectures

Multicore processors are increasingly adopted in embedded systems to meet growing performance demands. However, physical side-channel analysis of multicore architectures remains underexplored, as obtaining usable leakage is inherently challenging. Consequently, side-channel security research on...

Name of the Vulnerable Software and Affected Versions dovecot versions prior to 2.4.5-1.1 Description When IMAP compression is enabled, the compression state is reused across responses in a session. This causes response sizes to depend on both attacker-supplied mail and other mail within the same...

UBUNTU-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...

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 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...

Vulnerabilities of the functions tcp_inbound_md5_hash(), tcp_v4_send_reset(), and tcp_v6_send_reset() in the Linux operating system, allowing attackers to compromise the confidentiality, integrity, and accessibility of protected information

The vulnerabilities of the functions tcpinboundmd5hash, tcpv4sendreset, and tcpv6sendreset in the Linux operating system are related to the disclosure of information due to the observed difference in execution time. Exploiting these vulnerabilities can allow a remote attacker to compromise the...

MCSI: A Masked Commutative Supersingular Isogeny Key Exchange with Blinded Ephemeral Keys

We introduce MCSI, a two message key exchange we design over the CSIDH class group action, in which each party sends its ephemeral public element under an authenticated encryption keyed by the value the two static keys determine. The design gives implicit mutual authentication, hides the ephemera...
