**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a potential use-after-free problem in the Linux kernel's aoe module, specifically in the tx() function. This problem can be exploited by a remote attacker to execute arbitrary code or cause a denial of service. The vulnerability is caused by incorrect reference counting of the net device structure object. The estimated number of potentially affected devices worldwide is not available. There is no information about real-world incidents where this issue was exploited. **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 versions 3.11 and later **Description** The issue is related to incorrect initialization of data in the Linux operating system, which can lead to a denial of service. The problem arises from the fix for a previous issue, where the initialization of pointers was implemented to prevent the use of uninitialized or stale values. However, this initialization may overwrite pointers that need to be cleaned up under certain conditions, resulting in a leak of persistent grants. This leak can prevent the full cleanup of resources after a guest has died, leaving behind zombie domains. **Recommendations** For Linux versions 3.11 and later, consider disabling the affected cleanup code as a temporary workaround until a proper fix is available. Restrict access to the vulnerable components to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
