CVE-2025-71076 Details
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)
A vulnerability in the Linux kernel's Direct Rendering Manager (DRM) Xe Open Allocation (OA) component allows userspace to send excessively large synchronization values. This lack of validation could lead to excessive memory allocations. The issue has been addressed by implementing a check to ensure that the number of synchronization parameters does not exceed the defined maximum limit, with the kernel returning an error when this limit is breached.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched version are available on the Linux Kernel Archive.
