CVE ID : CVE-2026-23210<\/p>\n
Published : Feb. 14, 2026, 5:15 p.m. | 1\u00a0hour, 14\u00a0minutes ago<\/p>\n
Description : In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
ice: Fix PTP NULL pointer dereference during VSI rebuild<\/p>\n
Fix race condition where PTP periodic work runs while VSI is being
\nrebuilt, accessing NULL vsi->rx_rings.<\/p>\n
The sequence was:
\n1. ice_ptp_prepare_for_reset() cancels PTP work
\n2. ice_ptp_rebuild() immediately queues PTP work
\n3. VSI rebuild happens AFTER ice_ptp_rebuild()
\n4. PTP work runs and accesses NULL vsi->rx_rings<\/p>\n
Fix: Keep PTP work cancelled during rebuild, only queue it after
\nVSI rebuild completes in ice_rebuild().<\/p>\n
Added ice_ptp_queue_work() helper function to encapsulate the logic
\nfor queuing PTP work, ensuring it’s only queued when PTP is supported
\nand the state is ICE_PTP_READY.<\/p>\n
