CVE-2025-71076: drm/xe/oa: Limit num_syncs to prevent oversized allocations
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/oa: Limit numsyncs to prevent oversized allocations
The OA open parameters did not validate numsyncs, allowing userspace to pass arbitrarily large values, potentially leading to excessive allocations.
Add check to ensure that numsyncs does not exceed DRMXEMAXSYNCS, returning -EINVAL when the limit is violated.
v2: use XEIOCTLDBG() and drop duplicated check. (Ashutosh)
(cherry picked from commit e057b2d2b8d815df3858a87dffafa2af37e5945b)
