Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The vulnerability is related to errors in memory deallocation in the wilc1000 component of the Linux kernel. This issue can cause a denial of service. The problem arises from the reallocation of the workqueue every time an interface is added, which can lead to the overwriting of the workqueue with a new one. This can be observed by running specific commands that add and remove interfaces, resulting in multiple workqueue instances being created. To fix this leakage, the allocation of hif workqueue has been moved back to wilc cfg80211 init. The workqueue name has also been modified to include the wiphy name for clarity.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
