"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nice: Fix PTP NULL pointer dereference during VSI rebuild\n\nFix race condition where PTP periodic work runs while VSI is being\nrebuilt, accessing NULL vsi->rx_rings.\n\nThe 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\n\nFix: Keep PTP work cancelled during rebuild, only queue it after\nVSI rebuild completes in ice_rebuild().\n\nAdded 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.\n\nError log:\n[ 121.392544] ice 0000:60:00.1: PTP reset successful\n[ 121.392692] BUG: kernel NULL pointer dereference, address: 0000000000000000\n[ 121.392712] #PF: supervisor read access in kernel mode\n[ 121.392720] #PF: error_code(0x0000) - not-present page\n[ 121.392727] PGD 0\n[ 121.392734] Oops: Oops: 0000 [#1] SMP NOPTI\n[ 121.392746] CPU: 8 UID: 0 PID: 1005 Comm: ice-ptp-0000:60 Tainted: G S 6.19.0-rc6+ #4 PREEMPT(voluntary)\n[ 121.392761] Tainted: [S]=CPU_OUT_OF_SPEC\n[ 121.392773] RIP: 0010:ice_ptp_update_cached_phctime+0xbf/0x150 [ice]\n[ 121.393042] Call Trace:\n[ 121.393047] <TASK>\n[ 121.393055] ice_ptp_periodic_work+0x69/0x180 [ice]\n[ 121.393202] kthread_worker_fn+0xa2/0x260\n[ 121.393216] ? __pfx_ice_ptp_periodic_work+0x10/0x10 [ice]\n[ 121.393359] ? __pfx_kthread_worker_fn+0x10/0x10\n[ 121.393371] kthread+0x10d/0x230\n[ 121.393382] ? __pfx_kthread+0x10/0x10\n[ 121.393393] ret_from_fork+0x273/0x2b0\n[ 121.393407] ? __pfx_kthread+0x10/0x10\n[ 121.393417] ret_from_fork_asm+0x1a/0x30\n[ 121.393432] </TASK>"
