CVE-2025-38374

CVE-2025-38374 – Linux kernel (OP-TEE FF-A): The issue arises because OP-TEE’s notif_callback() for FF-A notifications was executed in an atomic context, leading to a sleep and a kernel warning. The fix is to move notification processing to a non-atomic context by using a work queue. Affected des...

LURK-T: Limited Use of Remote Keys with Added Trust in TLS 1.3

In many web applications, such as Content Delivery Networks CDNs, TLS credentials are shared, e.g., between the website's TLS origin server and the CDN's edge servers, which can be distributed around the globe. To enhance the security and trust for TLS 1.3 in such scenarios, we propose LURK-T, a...
