CVE-2026-43384

The CVE-2026-43384 issue concerns the Linux kernel TCP Authentication Option (TCP-AO) where MACs were compared without constant-time handling. The connected documents confirm a fix was applied to make MAC comparisons constant-time, mitigating timing-attack leakage of sensitive information. The vu...

PT-2026-39044

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A timing attack is possible because Message Authentication Codes MACs are not compared in constant time. This allows an attacker to potentially deduce information by measuring the time t...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fact that the MAC comparison in tcp-ao does not use a constant time, potentially leading to timing...

GHSA-53HJ-R94P-8C8F Kanidm has non-constant-time comparison of OAuth2 client_secret

Summary The kanidmd OAuth2 token-exchange /oauth2/token and token-introspection /oauth2/token/introspect endpoints compare the supplied clientsecret against the stored secret using Rust's PartialEq on String, which short-circuits on the first mismatching byte. This produces an observable timing...

GHSA-248H-974Q-XRC2 axonflow-sdk-java: Webhook signing-key (HMAC-SHA256) not exposed by SDK type, preventing signature verification

Summary The AxonFlow SDK's WebhookSubscription or equivalent type did not expose the HMAC-SHA256 signing key returned by the platform's CreateWebhook endpoint. Without access to the secret through the typed SDK API, callers had no path to verify the X-AxonFlow-Signature header on incoming webhook...
