Memory Corruption Vulnerability in Linux Kernel Affects Task Management

CVE-2025-21919

Summary

A vulnerability in the Linux kernel's task management could result in memory corruption due to improper handling of pointer conversions within the CFS scheduler. The issue is triggered during the manipulation of lists associated with child scheduling classes, potentially leading to unpredictable behavior and access to corrupted data. Fixes ensure that a check is in place during pointer operations to validate the integrity of the cfs_rq structures, preventing mishaps and enhancing operational stability.
