Vulnerability from github – Published: 2024-07-12 15:31 – Updated: 2025-11-04 00:30

Details

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.

Severity

5.5 (Medium)
