Vulnerability Title
gve: add missing NULL check for gve_alloc_pending_packet() in TX DQO
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: gve: add missing NULL check for gve_alloc_pending_packet() in TX DQO gve_alloc_pending_packet() can return NULL, but gve_tx_add_skb_dqo() did not check for this case before dereferencing the returned pointer. Add a missing NULL check to prevent a potential NULL pointer dereference when allocation fails. This improves robustness in low-memory scenarios.
