Linux kernel may leave storage controller resources after removal

CVE-2023-53127 · published 1 year ago
Summary

The Linux kernel’s MPI3 storage driver could fail to clean up certain internal objects when a device is removed, potentially causing a small memory leak. This leak is unlikely to affect stability but could accumulate over time on systems that frequently add and remove such devices. Updating to a kernel version that includes the fix will resolve the issue.

What to do
  • Update debian linux to version 6.1.25-1.
  • Update linux kernel to version 6.2.8.
