CVE-2021-47141

A vulnerability was found in the Generic Virtual Ethernet (gve) driver in the Linux kernel. A NULL pointer dereference could occur during the freeing of notification blocks. This issue arises when attempting to index priv->msix_vectors without prior allocation, potentially leading to a crash if the driver is unloaded.

Mitigation

To mitigate this issue, NULL pointer checks have been added to ensure safe handling during the freeing process of notification blocks within the gve driver. It is advised to update the affected package as soon as possible.
