CVE-2026-63910

A flaw was found in the Linux kernel's dma-buf Direct Memory Access buffer subsystem. A race condition in the dmabuffd tracepoint can lead to a Use-After-Free UAF vulnerability. A local attacker could exploit this by closing a file descriptor fd prematurely, causing the dmabuf to be freed while t...
