Vulnerability CVE-2024-42139
Published: 2024-07-30
| Description: |
In the Linux kernel, the following vulnerability has been resolved:
ice: Fix improper extts handling
Extts events are disabled and enabled by the application ts2phc.
However, in case where the driver is removed when the application is
running, a specific extts event remains enabled and can cause a kernel
crash.
As a side effect, when the driver is reloaded and application is started
again, remaining extts event for the channel from a previous run will
keep firing and the message "extts on unexpected channel" might be
printed to the user.
To avoid that, extts events shall be disabled when PTP is released. |
