CVE-2024-40967 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-cross-headers package and not the kernel-cross-headers package as distributed by RHEL.
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.
