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

ice: Fix increasing MSI-X on VF

Increasing MSI-X value on a VF leads to invalid memory operations. This is caused by not reallocating some arrays.

Reproducer: modprobe ice echo 0 > /sys/bus/pci/devices/$PF_PCI/sriov_drivers_autoprobe echo 1 > /sys/bus/pci/devices/$PF_PCI/sriov_numvfs echo 17 > /sys/bus/pci/devices/$VF0_PCI/sriov_vf_msix_count

Default MSI-X is 16, so 17 and above triggers this issue.

KASAN reports:
