CVE-2023-52916

Summary

In the Linux kernel, the following vulnerability has been resolved:

media: aspeed: Fix memory overwrite if timing is 1600x900

When capturing 1600x900, system could crash when system memory usage is tight.

The way to reproduce this issue:

  1. Use 1600x900 to display on host
  2. Mount ISO through 'Virtual media' on OpenBMC's web
  3. Run script as below on host to do sha continuously #!/bin/bash while [ [1] ]; do find /media -type f -printf '"%h/%f"\n' | xargs sha256sum done
  4. Open KVM on OpenBMC's web

The size of macro block captured is 8x8. Therefore, we should make sure the height of src-buf is 8 aligned to fix this issue.
