CVE-2024-35790: usb: typec: altmodes/displayport: create sysfs nodes as driver's default device attribute group

Published May 17, 2024
·
Updated

In the Linux kernel, the following vulnerability has been resolved:

usb: typec: altmodes/displayport: create sysfs nodes as driver's default device attribute group

The DisplayPort driver's sysfs nodes may be present to the userspace before typecaltmodesetdrvdata() completes in dpaltmodeprobe. This means that a sysfs read can trigger a NULL pointer error by deferencing dp->hpd in hpdshow or dp->lock in pinassignmentshow, as devgetdrvdata() returns NULL in those cases.

Remove manual sysfs node creation in favor of adding attribute group as default for devices bound to the driver. The ATTRIBUTEGROUPS() macro is not used here otherwise the path to the sysfs nodes is no longer compliant with the ABI.
