  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: typec: altmodes/displayport: validate count before reading Status Update VDO\n\nA broken/malicious device can send the incorrect count for a status\nupdate VDO, which will cause the kernel to read uninitialized stack data\nand send it off elsewhere.\n\nFix this up by correctly verifying the count for the update object.",
