Name of the Vulnerable Software and Affected Versions
Linux kernel version 5.2.14
Description
The issue is related to the
alloc workqueue component in the Linux kernel, which can lead to a NULL pointer dereference. This can potentially allow a remote attacker to cause a denial of service. The problem is specifically located in the drivers/net/wireless/intel/iwlwifi/pcie/trans.c file.Recommendations
For Linux kernel version 5.2.14, ensure that the return value of
alloc workqueue is properly checked to prevent NULL pointer dereferences. As a temporary workaround, consider implementing additional error checking mechanisms for the alloc workqueue function until a patch is available.Correção
