  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm: Account property blob allocations to memcg\n\nDRM_IOCTL_MODE_CREATEPROPBLOB allows userspace to allocate arbitrary-sized\nproperty blobs backed by kernel memory.\n\nCurrently, the blob data allocation is not accounted to the allocating\nprocess's memory cgroup, allowing unprivileged users to trigger unbounded\nkernel memory consumption and potentially cause system-wide OOM.\n\nMark the property blob data allocation with GFP_KERNEL_ACCOUNT so that the memory\nis properly charged to the caller's memcg. This ensures existing cgroup\nmemory limits apply and prevents uncontrolled kernel memory growth without\nintroducing additional policy or per-file limits.",
