Details

Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux
kernel contained a race condition during device removal, leading to a use-
after-free vulnerability. A physically proximate attacker could possibly
use this to cause a denial of service (system crash). (CVE-2023-47233)
