**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a deadlock scenario in the Linux kernel's dma-debug component. The ` dma entry alloc check leak()` function calls into `printk` and grabs the `port->lock` under the `free entries lock` spin lock, creating a reverse locking dependency chain. This can lead to a deadlock when the qcom geni IRQ handler calls into dma-debug code and grabs the `free entries lock` under the `port->lock`. The vulnerability can cause a denial of service. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the drm/virtio component of the Linux kernel, where userspace can guess the handle value and try to race GEM object creation with handle close, resulting in a use-after-free if the object is dereferenced after dropping the handle's reference. This can potentially impact confidentiality, integrity, and availability. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
