GHSA-8QF2-P2J7-QP5X

Vulnerability from github – Published: 2024-07-30 09:32 – Updated: 2024-12-11 15:31

Details

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.

Severity ?

5.5 (Medium)
