CVE-2026-23317

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

drm/vmwgfx: Return the correct value in vmw_translate_ptr functions

Before the referenced fixes these functions used a lookup function that

returned a pointer. This was changed to another lookup function that

returned an error code with the pointer becoming an out parameter.

The error path when the lookup failed was not changed to reflect this

change and the code continued to return the PTR_ERR of the now

uninitialized pointer. This could cause the vmw_translate_ptr functions

to return success when they actually failed causing further uninitialized

and OOB accesses.
