CVE-2026-68262

In the Linux kernel, the following vulnerability has been resolved:

drm/imagination: Fix user array stride in pvr_set_uobj_array()

pvr_set_uobj_array() copies an array of kernel objects to a userspace

array whose element size is described by out->stride. When out->stride

is different from the kernel object size, the slow path advances the

userspace pointer by the kernel object size and the kernel pointer by the

userspace stride.

This reverses the intended layout. For larger userspace strides, later

copies read from the wrong kernel addresses. For smaller userspace

strides, later copies are written at the wrong userspace offsets. The

padding clear is also done only for the first element instead of the

padding area for each element.

Advance the userspace pointer by out->stride and the kernel pointer by

obj_size, and clear per-element padding while the current userspace

pointer is still available.
