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. A flaw was found in the Linux kernel's USB Type-C DisplayPort (DP) alternate mode. A malicious or improperly configured USB-C device can send a malformed status update Vendor Defined Object (VDO), which is a data structure used for communication. This can cause the kernel to read uninitialized memory from the stack and transmit this sensitive data, leading to information disclosure. This vulnerability allows an attacker with physical access to a malicious USB-C device to potentially gain access to sensitive system information.
