Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU85682
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-46838
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows an unprivileged guest to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of network packets at the backend. An unprivileged guest can send zero-length packets to the OS kernel and perform a denial of service (DoS) attack.
MitigationInstall updates from vendor's repository.

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: #VU88378
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-52340
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error when processing very large ICMPv6 packets. A remote attacker can send a flood of IPv6 ICMP6 PTB messages, cause the high lock contention and increased CPU usage, leading to a denial of service.
Successful vulnerability exploitation requires a attacker to be on the local network or have a high bandwidth connection.

EUVDB-ID: #VU86577
Risk: Low
CVSSv3.1: 7.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2024-1086
CWE-ID:
CWE-416 - Use After Free
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the netfilter nf_tables component in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code on the system.
MitigationInstall updates from vendor's repository.
