CVE-2026-72305

Estado: RecibidaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

VDUSE: avoid leaking information to userspace

The bounceing is not necessarily page aligned, so current VDUSE can leak kernel information through mapping bounce pages to userspace. Allocate bounce pages with __GFP_ZERO to avoid leaking information to userspace.
