memory cgroup

The memory cgroup (memcg) tag on WindowsForum.com covers Linux kernel memory control group functionality, including security vulnerabilities and patches. A key topic is CVE-2024-45021, a defect in the memcg event-control path that could be triggered by an unprivileged local user to cause a kernel oops. The fix was applied in upstream stable trees and by multiple distributors in September 2024. Memory cgroups are a long-standing Linux kernel facility for accounting and controlling memory use per cgroup, and discussions focus on their security, stability, and maintenance.
