Buffer Size Vulnerability in Linux Kernel Affects AMD Hardware

CVE-2026-74419

What is CVE-2026-74419?

A vulnerability in the Linux kernel affects the functionality of user space data handling for AMD devices. When applications request data, the functionality did not ensure that the size of the buffer was respected. This flaw resulted in the potential for excessive data being copied to user space, risking unintended behavior or system instability. Developers are encouraged to update to the latest kernel version where this issue has been addressed, ensuring that data returned adheres to the buffer size limitations specified by applications.
