CVE-2026-46309

A flaw was found in the Linux kernel's drm/xe/uapi component. This vulnerability allows a Graphics Processing Unit (GPU) using coh_none coherency mode to bypass CPU caches and read stale sensitive data directly from Dynamic Random-Access Memory (DRAM). This can lead to information disclosure, where data from previously freed pages of other processes may be leaked.
