SUSE CVE-2025-40204

In the Linux kernel, the following vulnerability has been resolved: sctp: Fix MAC comparison to be constant-time To prevent timing attacks, MACs need to be compared in constant time. Use the appropriate helper function for this...

Siemens RUGGEDCOM ROS Devices Observable Timing Discrepancy (CVE-2021-42016)

A timing attack, in a third-party component, could make the retrieval of the private key possible, used for encryption of sensitive data. If a threat actor were to exploit this, the data integrity and security could be compromised. This plugin only works with Tenable.ot. Please visit...

Django: User enumeration via timing attack in Django mod_wsgi authentication backend leads to account discovery

A vulnerability was discovered in the checkpassword function in django/contrib/auth/handlers/modwsgi.py. When a non-existent username was provided, the function returned immediately without performing password verification, leading to a timing attack that allowed attackers to enumerate valid...
