libcurl 8.11.0 < 8.21.0 HTTP/3 Early Data Information Disclosure (CVE-2026-9545)

The version of libcurl installed on the remote host is 8.11.0 prior to 8.21.0. It is, therefore, affected by an information disclosure vulnerability: - When libcurl returns to a hostname with a cached SSL session and early data enabled, libcurl might send the request bytes before enforcing the...

AI Attacks Move in Minutes. Join This Webinar on Building a Defense That Keeps Up

AI has changed how fast attacks move. Work that once took an attacker days now takes minutes. Using models like Mythos, attackers write tailored bait, pick targets, test what lands, and jump to the next host before your team clears the first alert. That is the gap, and it is not your fault. The...

kernel: RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event()

A flaw was found in the Linux kernel's RDMA/mlx4 component. This vulnerability arises from the incorrect use of Read-Copy Update RCU in the mlx4srqevent function. An attacker could potentially trigger an event before the srq object is fully initialized, leading to a system crash. This could resul...

CVE-2026-9545

A flaw was found in libcurl. An attacker can exploit this by replacing a legitimate HTTP/3 server with an impostor machine. When libcurl attempts a second transfer to the same site with a cached SSL session and early data enabled, it may send sensitive request data before verifying the server's...
