Description

In the Linux kernel, the following vulnerability has been resolved: gve: Clear napi->skb before dev_kfree_skb_any() gve_rx_free_skb incorrectly leaves napi->skb referencing an skb after it is freed with dev_kfree_skb_any(). This can result in a subsequent call to napi_get_frags returning a dangling pointer. Fix this by clearing napi->skb before the skb is freed.

Affected configurations

• linux linux kernel (>= 5.14 < 5.15.162) • linux linux kernel (>= 5.16 < 6.1.95) • linux linux kernel (>= 6.2 < 6.6.35) • linux linux kernel (>= 6.7 < 6.9.6) • linux linux kernel 6.10
