CVE-2026-89621

A flaw was found in the Linux kernel's HID Human Interface Device mcp2221 driver. A malicious USB device can exploit this vulnerability by sending a specially crafted, short HID report with an invalid size. This can cause the system to read past valid memory, leading to the disclosure of sensitiv...

CVE-2026-89623

A flaw was found in the Linux kernel's HID Human Interface Device mcp2221 driver. This vulnerability occurs when the device's input/output IO operations are not properly stopped before hardware teardown during device removal or probe failure. This timing issue can lead to a use-after-free...

CVE-2026-89622

A flaw was found in the Linux kernel's HID Human Interface Device subsystem, specifically in the mcp2221 driver. This vulnerability occurs because the driver fails to clear a buffer pointer after an I2C/SMBus transfer completes. A local attacker could exploit this by triggering a delayed or...
