Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.8.0-rc7

Description The vulnerability is related to the btnxpuart component in the Linux kernel, specifically with the btnxpuart close() function. It is caused by improper input validation, which can lead to a denial of service. The issue is resolved by properly purging the transmit queue and freeing the receive skb in the btnxpuart close() function.

Recommendations To resolve the issue, update the Linux kernel to a version that includes the fix for the btnxpuart close() function. As a temporary workaround, consider disabling the btnxpuart close() function until a patch is available.
