Ubuntu.comUB:CVE-2021-47017CVE-2021-47017
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.
