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

scsi: mpi3mr: Sanitise num_phys

Information is stored in mr_sas_port->phy_mask, values larger then size of
this field shouldn't be allowed.

A vulnerability was found in the Linux kernel's mpi3mr driver in the mpi3mr_sas_port_add() function, where a lack of proper checks could lead to values that are larger than what the defined size of the num_phys field in the mr_sas_node structure being inserted, causing the field to be overwritten and potentially corrupting the structure.
