Out-of-Bounds Write in Linux kernel (CVE-2023-52916)
Summary
Out-of-bounds write in Linux kernel (CVE-2023-52916). Successful exploitation can lead to full system takeover.
Original description
The description as published by the source.
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:
- Use 1600x900 to display on host
- Mount ISO through 'Virtual media' on OpenBMC's web
- 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 - 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.
