Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_buffers: Fix memory corruptions on Spectrum-4 systems
The following two shared buffer operations make use of the Shared Buffer
Status Register (SBSR):
# devlink sb occupancy snapshot pci/0000:01:00.0
# devlink sb occupancy clearmax pci/0000:01:00.0
The register has two masks of 256 bits to denote on which ingress /
egress ports the register should operate on. Spectrum-4 has more than
256 ports, so the register was extended by cited commit with a new
'port_page' field.
However, when filling the register's payload, the driver specifies the
ports as absolute numbers and not relative to the first port of the port
page, resulting in memory corruptions [1].
Fix by specifying the ports relative to the first port of the port page.
