CVE-2020-36158
mwifiex_cmd_802_11_ad_hoc_start in drivers/net/wireless/marvell/mwifiex/join.c in the Linux kernel through 5.10.4 might allow remote attackers to execute arbitrary code via a long SSID value, aka CID-5c455c5ab332.
Does this matter?
Lower severity and a low EPSS score (2.31%). Track it; it rarely justifies an emergency change on its own.
