Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU82755

Risk: Low

CVSSv3.1: 5.9 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-47233

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows an attacker to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the brcm80211 in a brcmf_cfg80211_detach in the device unplugging (disconnect the USB by hotplug) code. An attacker with physical access to device can trigger a use-after-free error and escalate privileges on the system.

Mitigation

Update the affected package linux to the latest version.
