Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The
DRM IOCTL MODE CREATEPROPBLOB ioctl allows userspace to allocate arbitrary-sized property blobs using kernel memory. Because these allocations are not accounted to the allocating process's memory cgroup (memcg), unprivileged users can trigger unbounded kernel memory consumption, potentially leading to a system-wide Out-Of-Memory (OOM) condition, where the system runs out of available memory and begins terminating processes to recover.Recommendations
Mark the property blob data allocation with
GFP KERNEL ACCOUNT to ensure memory is properly charged to the caller's memcg. Found an issue in the description? Have something to add? Feel free to write us 👾
