GHSA-X8FW-RVR9-2HX5

Vulnerability from github – Published: 2024-07-30 09:31 – Updated: 2025-01-08 21:32

Details

In the Linux kernel, the following vulnerability has been resolved:

ice: Don't process extts if PTP is disabled

The ice_ptp_extts_event() function can race with ice_ptp_release() and result in a NULL pointer dereference which leads to a kernel panic.

Panic occurs because the ice_ptp_extts_event() function calls ptp_clock_event() with a NULL pointer. The ice driver has already released the PTP clock by the time the interrupt for the next external timestamp event occurs.

To fix this, modify the ice_ptp_extts_event() function to check the PTP state and bail early if PTP is not ready.

Severity ?

4.7 (Medium)
