Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Buffer overflow
EUVDB-ID: #VU69803
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-3628
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the brcmf_fweh_event_worker() function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/fweh.c. A local user can use a specially crafted device to trigger memory corruption and escalate privileges on the system.
Install updates from vendor's repository.
