Buffer Management Issue in Linux Kernel Affecting Notification Handling

CVE-2025-68294

What is CVE-2025-68294?

A vulnerability in the Linux kernel related to vectored buffer imports has been identified, affecting how notification handling is managed. Specifically, the issue arises from the import procedure using 'req' rather than the corresponding notification io_kiocb, which is correctly utilized for non-vectored imports. This oversight could lead to inconsistencies in the lifecycle management of vectored buffers, potentially compromising system stability and security. It is crucial for system administrators and developers to apply the latest patches addressing this vulnerability to ensure the integrity of their systems.
