**Name of the Vulnerable Software and Affected Versions** Linux kernel versions through 5.5.3 **Description** The issue is related to the `ext4 protect reserved inode` function in the Linux kernel, which can lead to a denial of service (soft lockup) when exploited. This is caused by an uncontrolled resource consumption, allowing an attacker to disrupt the system. **Recommendations** For Linux kernel versions through 5.5.3, update to a version newer than 5.5.3 to resolve the issue. At the moment, there is no information about other specific mitigation measures for this vulnerability.
