- Summary
- usb: typec: altmodes/displayport: validate count before reading Status Update VDO
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: altmodes/displayport: validate count before reading Status Update VDO
A broken/malicious device can send the incorrect count for a status update VDO, which will cause the kernel to read uninitialized stack data and send it off elsewhere.
Fix this up by correctly verifying the count for the update object.
