CVE-2024-53052

Description

A flaw was found in the Linux kernel's io_uring subsystem. A local user with administrative privileges can cause a Denial of Service (DoS) by triggering a system deadlock. This issue occurs when direct input/output (I/O) write requests are processed during an active filesystem freeze without verifying non-blocking execution status. As a result, the freeze operation and pending write tasks wait on each other indefinitely, causing affected storage operations to hang.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
