Description

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.
