OESA-2023-1614 (CVE-2023-3865)

Vulnerability from osv_openeuler – Published: 2023-09-09 11:06 – Updated: 2026-08-06 11:06 – Source website

Summary

kernel security update

Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

(CVE-2023-3865)

(CVE-2023-3866)

A use-after-free vulnerability was found in the siano smsusb module in the Linux kernel. The bug occurs during device initialization when the siano device is plugged in. This flaw allows a local user to crash the system, causing a denial of service condition.(CVE-2023-4132)

A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation of the file name reconstruction function, which is responsible for reading file name entries from a directory index and merging file name parts belonging to one file into a single long file name. Since the file name characters are copied into a stack variable, a local privileged attacker could use this flaw to overflow the kernel stack.(CVE-2023-4273)

Severity

7.1 (High)

CVE-2023-3865 (GCVE-0-2023-3865)

Vulnerability from cvelistv5 – Published: 2025-08-16 13:27 – Updated: 2026-08-15 12:23

Title

ksmbd: fix out-of-bound read in smb2_write

Summary

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix out-of-bound read in smb2_write ksmbd_smb2_check_message doesn't validate hdr->NextCommand. If ->NextCommand is bigger than Offset + Length of smb2 write, It will allow oversized smb2 write length. It will cause OOB read in smb2_write.

Severity

8.1 (High)

CVE-2023-3866 (GCVE-0-2023-3866)

Vulnerability from cvelistv5 – Published: 2025-08-16 13:27 – Updated: 2026-08-05 09:09

Title

ksmbd: validate session id and tree id in the compound request

Summary

In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate session id and tree id in the compound request This patch validate session id and tree id in compound request. If first operation in the compound is SMB2 ECHO request, ksmbd bypass session and tree validation. So work->sess and work->tcon could be NULL. If secound request in the compound access work->sess or tcon, It cause NULL pointer dereferecing error.

Severity

7.5 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
