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

Executive Summary

This vulnerability in the Linux kernel's drm/xe/oa component involves a lack of validation for the 'num_syncs' parameter. Userspace could pass arbitrarily large values for 'num_syncs', which could lead to excessive memory allocations. The fix adds a check to ensure 'num_syncs' does not exceed a defined maximum (DRM_XE_MAX_SYNCS), returning an error if the limit is violated.

Impact Analysis

The vulnerability can lead to excessive memory allocations in the Linux kernel, which may cause resource exhaustion or denial of service conditions, potentially impacting system stability or availability.
