CVE-2026-68240

A flaw was found in the Linux kernel's drm/gpusvm component. When drmgpusvmgetpages encounters an error during page mapping, it fails to properly unmap previously created device mappings. This oversight can lead to a device mapping leak, consuming system resources and potentially impacting system...
