CVE-2026-72305

Consolidated details show CVE-2026-72305 affects the Linux kernel VDUSE subsystem, where bounce pages mapped to userspace may leak kernel information due to non-page-aligned bounce handling. Mitigation: allocate bounce pages with __GFP_ZERO to prevent leaking data to userspace. The vulnerability ...
