Описание
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.
A flaw was found in the Linux kernel's mwifiex driver implementation when connecting to other WiFi devices in "Test Mode." A kernel memory leak can occur if an error condition is met during the parameter negotiation. This issue can lead to a denial of service if multiple error conditions meeting the repeated connection attempts are attempted.
Меры по смягчению последствий
As connecting to a wireless device is not automatic and initiated by a user, not connecting to rogue access points would prevent this flaw from being abused.
