Linux kernel quota may access released memory
published 4 months ago
Summary
The part of the Linux kernel that tracks disk usage quotas could sometimes use a memory block that has already been freed. This can cause crashes or incorrect quota data when the system is under memory pressure. The kernel has been updated to ensure the memory is removed from the active list before it is accessed, eliminating the risk.
What to do
- Update echo linux to version 6.12.94-1.
