CVE-2023-21400

Опубликовано: 05 июл. 2023
Источник: redhat
CVSS3: 7

Описание

In multiple functions of io_uring.c, there is a possible kernel memory corruption due to improper locking. This could lead to local escalation of privilege in the kernel with System execution privileges needed. User interaction is not needed for exploitation.

A double-free vulnerability was found in the io_uring subsystem in the Linux kernel. This issue may allow a malicious local user to crash the kernel or elevate their privileges on the system.

Отчет

No Red Hat products are affected by this flaw, as the io_uring subsystem is not enabled in any shipping kernel release.
