3) Out-of-bounds read

EUVDB-ID: #VU79477

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-38430

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in ksmbd when handling SMB request protocol ID. A remote attacker can send specially crafted packets to the system to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.

Mitigation

Update the affected package linux to the latest version.

6) Out-of-bounds read

EUVDB-ID: #VU81661

Risk: Medium

CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-3865

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote user to gain access to potentially sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the ksmbd_smb2_check_message() function in fs/smb/server/smb2misc.c when parsing smb2_hdr structure. A remote user can send specially crafted packets to ksmbd, trigger an out-of-bounds read error and read contents of memory or perform a denial of service (DoS) attack.

Mitigation

Update the affected package linux to the latest version.

No. We are not aware of malware exploiting this vulnerability.

11) Buffer overflow

EUVDB-ID: #VU81660

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-44466

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the ceph_decode_32() function in net/ceph/messenger_v2.c in the Ceph filesystem when handling TCP packets. A remote attacker can send specially crafted HELLO or AUTH frames to trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected package linux to the latest version.
