OESA-2024-1086 (CVE-2023-51779)

Vulnerability from osv_openeuler – Published: 2024-01-19 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):

A flaw was found in the Bluetooth subsystem of the Linux kernel. A race condition between the bt_sock_recvmsg() and bt_sock_ioctl() functions could lead to a use-after-free on a socket buffer ("skb"). This flaw allows a local user to cause a denial of service condition or potential code execution.(CVE-2023-51779)

An issue was discovered in the Linux kernel before 6.6.8. do_vcc_ioctl in net/atm/ioctl.c has a use-after-free because of a vcc_recvmsg race condition.(CVE-2023-51780)

An issue was discovered in the Linux kernel before 6.6.8. atalk_ioctl in net/appletalk/ddp.c has a use-after-free because of an atalk_recvmsg race condition.(CVE-2023-51781)

An issue was discovered in the Linux kernel before 6.6.8. rose_ioctl in net/rose/af_rose.c has a use-after-free because of a rose_accept race condition.(CVE-2023-51782)

An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).(CVE-2023-6121)

Severity

7.8 (High)

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.
