| Vector | AV:L/AC:L/Au:S/C:N/I:N/A:P |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the drm/xe subsystem related to handling the
num syncs parameter in the exec and vm bind ioctl calls. Without proper bounds checking, a large num syncs value supplied by userspace can trigger an excessively large memory allocation, potentially leading to kernel warnings from the page allocator. The issue is addressed by introducing a limit, DRM XE MAX SYNCS, set to 1024, and rejecting requests exceeding this limit. The vulnerable code resides in the xe exec ioctl function.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
