Description : In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
can: hi311x: fix null pointer dereference when resuming from sleep before interface was enabled<\/p>\n
This issue is similar to the vulnerability in the `mcp251x` driver,
\nwhich was fixed in commit 03c427147b2d (“can: mcp251x: fix resume from
\nsleep before interface was brought up”).<\/p>\n
In the `hi311x` driver, when the device resumes from sleep, the driver
\nschedules `priv->restart_work`. However, if the network interface was
\nnot previously enabled, the `priv->wq` (workqueue) is not allocated and
\ninitialized, leading to a null pointer dereference.<\/p>\n
To fix this, we move the allocation and initialization of the workqueue
\nfrom the `hi3110_open` function to the `hi3110_can_probe` function.
\nThis ensures that the workqueue is properly initialized before it is
\nused during device resume. And added logic to destroy the workqueue
\nin the error handling paths of `hi3110_can_probe` and in the
\n`hi3110_can_remove` function to prevent resource leaks.<\/p>\n
Severity: 0.0 | NA<\/p>\n
