5) Out-of-bounds read

EUVDB-ID: #VU85443

Risk: Low

CVSSv3.1: 6.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-6610

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

Exploit availability: No

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to a boundary condition within the smb2_dump_detail() function in fs/smb/client/smb2ops.c. A local user can trigger an out-of-bounds read error and gain access to sensitive information or crash the kernel.

Mitigation

Update the affected package linux to the latest version.

CVSSv3.1: 7 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-52434

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the smb2_parse_contexts() function when parsing SMB packets. A remote user can send specially crafted SMB traffic to the affected system, trigger memory corruption and execute arbitrary code.

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

Mitigation

Update the affected package linux to the latest version.
