The fix, per the provided description, is to stop creating the unneeded attribute for the control devi...

CVE-2022-49329 vduse: Fix NULL pointer dereference on sysfs access

In the Linux kernel, the following vulnerability has been resolved: vduse: Fix NULL pointer dereference on sysfs access The control device has no drvdata. So we will get a NULL pointer dereference when accessing control device's msgtimeout attribute via sysfs: 132.841881 T3644 BUG: kernel NULL...

CVE-2022-49308

The CVE-2022-49308 entry describes a Linux kernel extcon overflow/NULL dereference vulnerability that could cause an Oops when sysfs state_show() runs before driver data is set. The root cause is extcon device creation occurring before drvdata is initialized, leading to an edev NULL dereference d...

CVE-2022-49308 extcon: Modify extcon device to be created after driver data is set

In the Linux kernel, the following vulnerability has been resolved: extcon: Modify extcon device to be created after driver data is set Currently, someone can invoke the sysfs such as stateshow intermittently before devsetdrvdata is done. And it can be a cause of kernel Oops because of edev is Nu...
