Description
A flaw was found in the Linux kernel's handling of filesystem errors. When a filesystem encounters an error and is configured to remount as read-only, the kernel's attempt to apply this setting can conflict with other filesystem operations, specifically during filesystem freezing. This conflict can lead to system instability, potentially resulting in a denial of service where the system becomes unresponsive.
