The ice driver has already\nreleased the PTP clock by the time the interrupt for the next external\ntimestamp event occurs.\n\nTo fix this, modify the ice_ptp_extts_event() function to check the\nPTP state and bail early if PTP is not ready.\n\n## Affected\n\n- `Linux >= 172db5f91d5f7b91670c68a7547798b0b5374158 < 9aa83a5eb013f8aff20e701aa25ba6b0eaad0b65`\n- `Linux >= 172db5f91d5f7b91670c68a7547798b0b5374158 < 1c4e524811918600683b1ea87a5e0fc2db64fa9b`\n- `Linux >= 172db5f91d5f7b91670c68a7547798b0b5374158 < 996422e3230e41468f652d754fefd1bdbcd4604e`\n- `Linux 5.14`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
