CVE-2026-68268: Linux

Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Return error on non-migratable faults requiring devmem Non-migratable faults that require devmem incorrectly jump to the 'out' label, which squashes the error code intended to be returned to the upper layers. Fix this by returning -EACCES instead. (cherry picked from commit c4508edb2c723de93717272488ea65b165637eac)
