Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
EUVDB-ID: #VU69756
Risk: Medium
CVSSv4.0: 2.3 [CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-3524
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak within the ipv6_renew_options() function when retrieving a new IPv6 address from a malicious DHCP server. A remote attacker can force the system to leak memory and perform denial of service attack.
MitigationUpdate the affected package linux-oem-6.0 to the latest version.
Vulnerable software versionsUbuntu: 22.04
linux-image-oem-22.04b (Ubuntu package): before 6.0.0.1008.8
linux-image-6.0.0-1008-oem (Ubuntu package): before 6.0.0-1008.8
CPE2.3https://ubuntu.com/security/notices/USN-5780-1
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
EUVDB-ID: #VU69800
Risk: Low
CVSSv4.0: 0.4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-3619
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows an attacker to perform a DoS attack.
The vulnerability exists due memory leak within the l2cap_recv_acldata() function in net/bluetooth/l2cap_core.c. An attacker with physical proximity to device can force the system to leak memory and perform denial of service attack.
MitigationUpdate the affected package linux-oem-6.0 to the latest version.
Vulnerable software versionsUbuntu: 22.04
linux-image-oem-22.04b (Ubuntu package): before 6.0.0.1008.8
linux-image-6.0.0-1008-oem (Ubuntu package): before 6.0.0-1008.8
CPE2.3https://ubuntu.com/security/notices/USN-5780-1
Q & A
Can this vulnerability be exploited remotely?
No. The attacker should have physical access to the system in order to successfully exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
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.
Update the affected package linux-oem-6.0 to the latest version.
Vulnerable software versionsUbuntu: 22.04
linux-image-oem-22.04b (Ubuntu package): before 6.0.0.1008.8
linux-image-6.0.0-1008-oem (Ubuntu package): before 6.0.0-1008.8
CPE2.3https://ubuntu.com/security/notices/USN-5780-1
Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
EUVDB-ID: #VU69796
Risk: Low
CVSSv4.0: 0.4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-42895
CWE-ID:
CWE-824 - Access of Uninitialized Pointer
Exploit availability: No
DescriptionThe vulnerability allows an attacker to gain access to sensitive information.
The vulnerability exists due to unauthorized access of uninitialized pointer within the l2cap_parse_conf_req() function in net/bluetooth/l2cap_core.c. An attacker with physical proximity to the affected device can gain access to sensitive information.
Update the affected package linux-oem-6.0 to the latest version.
