CVE-2024-46749

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btnxpuart: Fix Null pointer dereference in btnxpuart_flush()

This adds a check before freeing the rx-&gt;skb in flush and close
functions to handle the kernel crash seen while removing driver after FW
download fails or before FW download completes.

CVE-2024-46749

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btnxpuart: Fix Null pointer dereference in btnxpuart_flush()

This adds a check before freeing the rx->skb in flush and close
functions to handle the kernel crash seen while removing driver after FW
download fails or before FW download completes.
