There is no fixed version for Centos:7 kernel-rt-trace-devel.

NVD Description

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.
