CVE-2026-89470

A flaw was found in the Linux kernel's crosusbpd-charger driver. This driver, which manages USB power delivery, incorrectly processes port count information from an embedded controller. A malicious embedded controller could provide an exaggerated port count, leading to an out-of-bounds write and...

CVE-2026-89471

A flaw was found in the Linux kernel's crosusbpd-charger driver. A malicious or compromised embedded controller EC can report an excessive number of USB Power Delivery PD ports. This causes the driver to write beyond the allocated memory buffer when populating a fixed-size array for port data,...

CVE-2026-89470

In the Linux kernel, the following vulnerability has been resolved: power: supply: crosusbpd: Limit port counts to ECUSBPDMAXPORTS Currently the crosusbpd-charger driver probe iterates based on raw charger port count returned by the embedded controller. The only check is against the number of USB...

CVE-2026-89471

In the Linux kernel, the following vulnerability has been resolved: power: supply: crosusbpd-charger: bound the EC-reported port count crosusbpdchargerprobe reads two port counts from the EC and uses one of them, numchargerports, as the loop bound when populating a fixed-size array: struct portda...

CVE-2026-89470 power: supply: cros_usbpd: Limit port counts to EC_USB_PD_MAX_PORTS

In the Linux kernel, the following vulnerability has been resolved: power: supply: crosusbpd: Limit port counts to ECUSBPDMAXPORTS Currently the crosusbpd-charger driver probe iterates based on raw charger port count returned by the embedded controller. The only check is against the number of USB...

In the Linux kernel, the following vulnerability has been resolved: power: supply: crosusbpd: Limit port counts to ECUSBPDMAXPORTS Currently the crosusbpd-charger driver probe iterates based on raw charger port count returned by the embedded controller. The only check is against the number of USB...

CVE-2026-89470

Linux kernel cros_usbpd-charger driver (power/supply) fails to properly bound the charger port count returned by the embedded controller (EC) during probe. The only check is against the EC-defined USB PD port count, so a malicious EC can report an inflated port count (up to 255), causing an out-o...

CVE-2026-89471

CVE-2026-89471 affects the Linux kernel's cros_usbpd-charger driver (power: supply subsystem). In cros_usbpd_charger_probe(), the EC-reported num_charger_ports value is used as a loop bound to populate a fixed-size array ports[EC_USB_PD_MAX_PORTS] of 8 entries, but is never validated against that...
