CVE-2023-2194 (GCVE-0-2023-2194)

Vulnerability from cvelistv5 – Published: 2023-04-20 00:00 – Updated: 2025-04-23 16:22

Summary

An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The userspace "data->block[0]" variable was not capped to a number between 0-255 and was used as the size of a memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to crash the system or potentially achieve code execution.

Severity

6.7 (Medium)

CVE-2023-2235 (GCVE-0-2023-2235)

Vulnerability from cvelistv5 – Published: 2023-05-01 12:51 – Updated: 2026-08-07 18:47

Title

Use-after-free in Linux kernel's Performance Events subsystem

Summary

A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve local privilege escalation. The perf_group_detach function did not check the event's siblings' attach_state before calling add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability. We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2.

Severity

7.8 (High)

CVE-2023-28466 (GCVE-0-2023-28466)

Vulnerability from cvelistv5 – Published: 2023-03-15 00:00 – Updated: 2025-05-05 16:02

Summary

do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference).

Severity

7 (High)

CVE-2023-32233 (GCVE-0-2023-32233)

Vulnerability from cvelistv5 – Published: 2023-05-08 00:00 – Updated: 2025-05-05 15:58

Summary

In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled.

Severity

7.8 (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.
