Description

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