## Overview

mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c in the Linux kernel before 5.1.6 has some error-handling cases that did not free allocated hostcmd memory, aka CID-003b686ace82. This will cause a memory leak and denial of service.

## Affected

- `linux_kernel < 5.1.6`
- `leap = 15.1`
- `active_iq_unified_manager`
- `cloud_backup`
- `data_availability_services`
- `e-series_santricity_os_controller >= 11.0.0, <= 11.70.1`
- `hci_management_node`
- `solidfire`
- `steelstore_cloud_integrated_storage`
- `a700s_firmware`
- `8300_firmware`
- `8700_firmware`
- `a400_firmware`
- `h610s_firmware`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.1.6`
