Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 6.19. It arises when amdgpuhmmrangealloc fails; as a result, amdgpugemuserptrioctl directly returns -ENOMEM and skips cleanup, leaving behind GEM objects, bo-parent references on VM root, and MMU notifier registrations. This may lead to...

Linux kernel security vulnerabilities
