Summary

kernel security update

Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

uio: Fix use-after-free in uio_open

core-1 core-2

uio_unregister_device uio_open idev = idr_find() device_unregister(&idev->dev) put_device(&idev->dev) uio_device_release get_device(&idev->dev) kfree(idev) uio_free_minor(minor) uio_release put_device(&idev->dev) kfree(idev)

In the core-1 uio_unregister_device(), the device_unregister will kfree idev when the idev->dev kobject ref is 1. But after core-1 device_unregister, put_device and before doing kfree, the core-2 may get_device. Then: 1. After core-1 kfree idev, the core-2 will do use-after-free for idev. 2. When core-2 do uio_release and put_device, the idev will be double freed.

To address this issue, we can get idev atomic & inc idev reference with minor_lock.(CVE-2023-52439)

NULL Pointer Dereference vulnerability in Linux Linux kernel kernel on Linux, x86, ARM (net, bluetooth modules) allows Overflow Buffers. This vulnerability is associated with program files /net/bluetooth/rfcomm/core.C.

This issue affects Linux kernel: v2.6.12-rc2.

The UAF at get_device occurs before any driver-specific open hooks.\nUI:N - No separate victim action is required; the attacker triggers the race directly by opening the device while unregister runs.\nS:U - This is a same-host kernel heap UAF/double-free leading to privilege escalation within the kernel\u0027s security authority, not a VM/IOMMU/sandbox boundary escape.\nC:H - Use-after-free of struct uio_device lets the attacker reclaim and control the freed object contents, enabling arbitrary kernel memory disclosure primitives.\nI:H - The same UAF plus the documented double-free on put_device/uio_device_release enables heap corruption and arbitrary write/control-flow hijacking in the kernel.\nA:H - Dereferencing or double-freeing the reclaimed uio_device reliably causes kernel oops/panic even when not fully exploited for code execution."

Detection rules are retrieved from Rulezet.

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.
