CVE-2024-40967

low-risk
Published 2024-07-12

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.
