CVSSv3.1: 7.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-38427

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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

The vulnerability exists due to integer overflow within the deassemble_neg_contexts() function in fs/smb/server/smb2pdu.c in ksmbd. A remote attacker can send specially crafted data to ksmbd, trigger an integer overflow and execute arbitrary code on the target system.
