CVE-2023-47233

Status Candidate

Overview

The brcm80211 component in the Linux kernel through 6.5.10 has a brcmf_cfg80211_detach use-after-free in the device unplugging (disconnect the USB by hotplug) code. For physically proximate attackers with local access, this "could be exploited in a real world scenario." This is related to brcmf_cfg80211_escan_timeout_worker in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c.

Ubuntu Security Notice 6828-1 - 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. It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code.
