- Summary
- HID: mcp-2221: prevent UAF in delayed work
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
HID: mcp-2221: prevent UAF in delayed work
If the device is plugged/unplugged without giving time for mcp_init_work() to complete, we might kick in the devm free code path and thus have unavailable struct mcp_2221 while in delayed work.
Canceling the delayed_work item is enough to solve the issue, because cancel_delayed_work_sync will prevent the work item to requeue itself.
