Description
Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
A NULL pointer dereference vulnerability has been identified in the legacy NCM driver of the Linux kernel. This issue arises from a change in the net_device lifecycle management, which deferred the allocation of the net_device. As a result, the driver attempts to access the net_device before it is fully initialized, leading to a crash. The vulnerability affects the Linux kernel stable tree.
The vulnerability has been addressed in the official Linux Git repository. Users can upgrade to the latest version of the Linux kernel to apply the fix.
