Linux Kernel gve Driver NULL Pointer Dereference Vulnerability

Vulnerability

A vulnerability in the Linux kernel's gve driver can lead to a NULL pointer dereference. The issue arises in the function gve_tx_add_skb_dqo(), which fails to check if gve_alloc_pending_packet() returned NULL before accessing the pointer. This oversight could cause a crash when memory allocation fails, particularly in low-memory situations.

Impact

Exploitation of this vulnerability can cause a system crash due to a NULL pointer dereference.
