CVE-2024-53203 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: usb: typec: fix potential array underflow in ucsi_ccg_sync_control() The "command" variable can be controlled by the user via debugfs. The worry is that if con_index is zero then "&uc->ucsi->connector[con_index - 1]" would be an array underflow.. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
