Descriptions
In the Linux kernel, the following vulnerability has been resolved:
ath10k: Fix a use after free in ath10k_htc_send_bundle
In ath10k_htc_send_bundle, the bundle_skb could be freed by
dev_kfree_skb_any(bundle_skb). But the bundle_skb is used later
by bundle_skb->len.
As skb_len = bundle_skb->len, my patch replaces bundle_skb->len to
skb_len after the bundle_skb was freed.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ath10k: corrige un use after free en ath10k_htc_send_bundle En ath10k_htc_send_bundle, el paquete_skb podría ser liberado por dev_kfree_skb_any(bundle_skb). Pero el paquete_skb lo utiliza más tarde el paquete_skb->len. Como skb_len = bundle_skb->len, mi parche reemplaza bundle_skb->len por skb_len después de que se liberó el paquete_skb.
