| Vetor | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel version 5.2.14
Description
The issue is related to a component in the Linux kernel, specifically with the alloc workqueue, which can lead to a NULL pointer dereference. This could potentially allow a remote attacker to cause a denial of service.
Recommendations
For Linux kernel version 5.2.14, consider applying a patch that checks the return value of alloc workqueue to prevent a NULL pointer dereference. As a temporary workaround, restrict access to the vulnerable component to minimize the risk of exploitation.
