A vulnerability in the Linux kernel's drm/xe/uapi subsystem was resolved by adding validation to reject PAT indices with XE_COH_NONE coherency mode when applied to CPU cached memory. This issue could allow a GPU to bypass CPU caches and read stale sensitive data directly from DRAM, potentially leaking data from previously freed pages of other processes. The vulnerability affects multiple Linux kernel versions prior to 7.0.0-28.28 and related versions. A patch is available and should be applied to mitigate the risk.

The Linux kernel vulnerability CVE-2026-46309 involves improper handling of the PAT index with XE_COH_NONE coherency mode in the drm/xe/uapi subsystem's madvise ioctl. Specifically, the kernel did not reject PAT indices with XE_COH_NONE when applied to CPU cached memory, which is a security issue. This allowed the GPU to bypass CPU caches and read stale data directly from DRAM, potentially leaking sensitive information from previously freed pages of other processes. The fix adds validation in xe_vm_madvise_ioctl() to reject such PAT indices, aligning with existing validation in the vm_bind path. The vulnerability affects multiple Linux kernel versions prior to 7.0.0-28.28 and related builds. The patch is included in updated Linux kernel packages distributed by Ubuntu.
