CVE-2026-64051

The issue is in the Linux kernel’s accel/qaic driver. A bounds check was missing in remap_pfn_range called by qaic_gem_object_mmap, allowing (re)mapping beyond the VMA when the BO is large. This can yield use-after-free if munmap() only unmaps the VMA while extra mappings remain, enabling potenti...
