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

ice: Fix PTP NULL pointer dereference during VSI rebuild

Fix race condition where PTP periodic work runs while VSI is being rebuilt, accessing NULL vsi->rx_rings.

The sequence was:

  • ice_ptp_prepare_for_reset() cancels PTP work
  • ice_ptp_rebuild() immediately queues PTP work
  • VSI rebuild happens AFTER ice_ptp_rebuild()
  • PTP work runs and accesses NULL vsi->rx_rings

Fix: Keep PTP work cancelled during rebuild, only queue it after VSI rebuild completes in ice_rebuild().

Added ice_ptp_queue_work() helper function to encapsulate the logic for queuing PTP work, ensuring it's only queued when PTP is supported and the state is ICE_PTP_READY.

EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 8 repeat rows among the latest 100 are merged into the row they repeat. The 97 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
