CVE-2024-40967 Information

Description

In the Linux kernel the following vulnerability has been resolved:

serial: imx: Introduce timeout when waiting on transmitter empty

By waiting at most 1 second for USR2_TXDC to be set we avoid a potential deadlock.

In case of the timeout there is not much we can do so we simply ignore the transmitter state and optimistically try to continue.
