  3. CVE-2024-40937
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.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: gve: Borrar napi->skb antes de dev_kfree_skb_any() gve_rx_free_skb deja incorrectamente napi->skb haciendo referencia a un skb después de liberarlo con dev_kfree_skb_any(). Esto puede resultar en una llamada posterior a napi_get_frags que devuelva un puntero colgante. Solucione este problema borrando napi->skb antes de liberar el skb.
