Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.19 and 6.7.7

Description The issue concerns a null pointer dereference in the 'nvidia-shield' component of the Linux kernel. This occurs because the devm kasprintf() function returns a pointer to dynamically allocated memory, which can be NULL upon failure. To ensure the allocation was successful, it is necessary to check the pointer validity. A local network attack risk is associated with this issue.

Recommendations To resolve the issue, update the Linux kernel to version 6.6.19 or 6.7.7, or later. As a temporary workaround, consider restricting access to the 'nvidia-shield' component until a patch is available.
