| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.58
Description
A vulnerability in the Linux kernel's Hisilicon QM driver has been resolved. The issue occurs when the accelerator core reports a memory error, and the master ooo cannot be completely closed. To fix this, the driver needs to inject a qm error to close the master ooo before stopping the queue, preventing the device from accessing released memory.
Recommendations
For Linux kernel versions prior to 6.6.58, update to version 6.6.58 or later to resolve the issue. As a temporary workaround, consider modifying the driver to inject the qm error before stopping the queue to prevent the device from accessing released memory. Restrict access to the affected driver until the update is applied to minimize the risk of exploitation.
