Description Guilherme de Almeida Suckevicz 2020-05-06 19:19:17 UTC 
An issue was found in Linux kernel before 5.5.4. mwifiex_ret_wmm_get_status() in drivers/net/wireless/marvell/mwifiex/wmm.c allows a remote AP to trigger a heap-based buffer overflow because of an incorrect memcpy.

Mitigation:

In order to mitigate this issue, it is possible to prevent the affected code from being loaded by blacklisting the kernel module mwifiex. For instructions relating to how to blacklist a kernel module, refer to: https://access.redhat.com/solutions/41278
