"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nice: fix NULL pointer dereference in ice_reset_all_vfs()\n\nice_reset_all_vfs() ignores the return value of ice_vf_rebuild_vsi().\nWhen the VSI rebuild fails (e.g. during NVM firmware update via\nnvmupdate64e), ice_vsi_rebuild() tears down the VSI on its error path,\nleaving txq_map and rxq_map as NULL. The subsequent unconditional call\nto ice_vf_post_vsi_rebuild() leads to a NULL pointer dereference in\nice_ena_vf_q_mappings() when it accesses vsi->txq_map[0].\n\nThe single-VF reset path in ice_reset_vf() already handles this\ncorrectly by checking the return value of ice_vf_reconfig_vsi() and\nskipping ice_vf_post_vsi_rebuild() on failure.\n\nApply the same pattern to ice_reset_all_vfs(): check the return value\nof ice_vf_rebuild_vsi() and skip ice_vf_post_vsi_rebuild() and\nice_eswitch_attach_vf() on failure. The VF is left safely disabled\n(ICE_VF_STATE_INIT not set, VFGEN_RSTAT not set to VFACTIVE) and can\nbe recovered via a VFLR triggered by a PCI reset of the VF\n(sysfs reset or driver rebind).\n\nNote that this patch does not prevent the VF VSI rebuild from failing\nduring NVM update — the underlying cause is firmware being in a\ntransitional state while the EMP reset is processed, which can cause\nAdmin Queue commands (ice_add_vsi, ice_cfg_vsi_lan) to fail. This\npatch only prevents the subsequent NULL pointer dereference that\ncrashes the kernel when the rebuild does fail.\n\n crash> bt\n PID: 50795 TASK: ff34c9ee708dc680 CPU: 1 COMMAND: \"kworker/u512:5\"\n #0 [ff72159bcfe5bb50] machine_kexec at ffffffffaa8850ee\n #1 [ff72159bcfe5bba8] __crash_kexec at ffffffffaaa15fba\n #2 [ff72159bcfe5bc68] crash_kexec at ffffffffaaa16540\n #3 [ff72159bcfe5bc70] oops_end at ffffffffaa837eda\n #4 [ff72159bcfe5bc90] page_fault_oops at ffffffffaa893997\n #5 [ff72159bcfe5bce8] exc_page_fault at ffffffffab528595\n #6 [ff72159bcfe5bd10] asm_exc_page_fault at ffffffffab600bb2\n [exception RIP: ice_ena_vf_q_mappings+0x79]\n RIP: ffffffffc0a85b29 RSP: ff72159bcfe5bdc8 RFLAGS: 00010206\n RAX: 00000000000f0000 RBX: ff34c9efc9c00000 RCX: 0000000000000000\n RDX: 0000000000000000 RSI: 0000000000000010 RDI: ff34c9efc9c00000\n RBP: ff34c9efc27d4828 R8: 0000000000000093 R9: 0000000000000040\n R10: ff34c9efc27d4828 R11: 0000000000000040 R12: 0000000000100000\n R13: 0000000000000010 R14: R15:\n ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018\n #7 [ff72159bcfe5bdf8] ice_sriov_post_vsi_rebuild at ffffffffc0a85e2e [ice]\n #8 [ff72159bcfe5be08] ice_reset_all_vfs at ffffffffc0a920b4 [ice]\n #9 [ff72159bcfe5be48] ice_service_task at ffffffffc0a31519 [ice]\n #10 [ff72159bcfe5be88] process_one_work at ffffffffaa93dca4\n #11 [ff72159bcfe5bec8] worker_thread at ffffffffaa93e9de\n #12 [ff72159bcfe5bf18] kthread at ffffffffaa946663\n #13 [ff72159bcfe5bf50] ret_from_fork at ffffffffaa8086b9\n\n The panic occurs attempting to dereference the NULL pointer in RDX at\n ice_sriov.c:294, which loads vsi->txq_map (offset 0x4b8 in ice_vsi).\n\n The faulting VSI is an allocated slab object but not fully initialized\n after a failed ice_vsi_rebuild():\n\n crash> struct ice_vsi 0xff34c9efc27d4828\n netdev = 0x0,\n rx_rings = 0x0,\n tx_rings = 0x0,\n q_vectors = 0x0,\n txq_map = 0x0,\n rxq_map = 0x0,\n alloc_txq = 0x10,\n num_txq = 0x10,\n alloc_rxq = 0x10,\n num_rxq = 0x10,\n\n The nvmupdate64e process was performing NVM firmware update:\n\n crash> bt 0xff34c9edd1a30000\n PID: 49858 TASK: ff34c9edd1a30000 CPU: 1 COMMAND: \"nvmupdate64e\"\n #0 [ff72159bcd617618] __schedule at ffffffffab5333f8\n #4 [ff72159bcd617750] ice_sq_send_cmd at ffffffffc0a35347 [ice]\n #5 [ff72159bcd6177a8] ice_sq_send_cmd_retry at ffffffffc0a35b47 [ice]\n #6 [ff72159bcd617810] ice_aq_send_cmd at ffffffffc0a38018 [ice]\n #7 [ff72159bcd617848] ice_aq_read_nvm at ffffffffc0a40254 [ice]\n #8 \n---truncated---"
