| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nice: Fix increasing MSI-X on VF\n\nIncreasing MSI-X value on a VF leads to invalid memory operations. This\nis caused by not reallocating some arrays.\n\nReproducer:\n modprobe ice\n echo 0 > /sys/bus/pci/devices/$PF_PCI/sriov_drivers_autoprobe\n echo 1 > /sys/bus/pci/devices/$PF_PCI/sriov_numvfs\n echo 17 > /sys/bus/pci/devices/$VF0_PCI/sriov_vf_msix_count\n\nDefault MSI-X is 16, so 17 and above triggers this issue.\n\nKASAN reports:\n\n BUG: KASAN: slab-out-of-bounds in ice_vsi_alloc_ring_stats+0x38d/0x4b0 [ice]\n Read of size 8 at addr ffff8888b937d180 by task bash/28433\n (...)\n\n Call Trace:\n (...)\n ? ice_vsi_alloc_ring_stats+0x38d/0x4b0 [ice]\n kasan_report+0xed/0x120\n ? ice_vsi_alloc_ring_stats+0x38d/0x4b0 [ice]\n ice_vsi_alloc_ring_stats+0x38d/0x4b0 [ice]\n ice_vsi_cfg_def+0x3360/0x4770 [ice]\n ? mutex_unlock+0x83/0xd0\n ? __pfx_ice_vsi_cfg_def+0x10/0x10 [ice]\n ? __pfx_ice_remove_vsi_lkup_fltr+0x10/0x10 [ice]\n ice_vsi_cfg+0x7f/0x3b0 [ice]\n ice_vf_reconfig_vsi+0x114/0x210 [ice]\n ice_sriov_set_msix_vec_count+0x3d0/0x960 [ice]\n sriov_vf_msix_count_store+0x21c/0x300\n (...)\n\n Allocated by task 28201:\n (...)\n ice_vsi_cfg_def+0x1c8e/0x4770 [ice]\n ice_vsi_cfg+0x7f/0x3b0 [ice]\n ice_vsi_setup+0x179/0xa30 [ice]\n ice_sriov_configure+0xcaa/0x1520 [ice]\n sriov_numvfs_store+0x212/0x390\n (...)\n\nTo fix it, use ice_vsi_rebuild() instead of ice_vf_reconfig_vsi(). This\ncauses the required arrays to be reallocated taking the new queue count\ninto account (ice_vsi_realloc_stat_arrays()). Set req_txq and req_rxq\nbefore ice_vsi_rebuild(), so that realloc uses the newly set queue\ncount.\n\nAdditionally, ice_vsi_rebuild() does not remove VSI filters\n(ice_fltr_remove_all()), so ice_vf_init_host_cfg() is no longer\nnecessary." |
