A FreeBSD eliminates<\/a><\/noindex> A USB stack vulnerability (CVE-2020-7456) that allows executing code at the kernel level or in user space when a malicious USB device is connected to the system. USB HID (Human Interface Device) descriptors can place and extract the current state, allowing the descriptions of elements to be combined into hierarchical groups. FreeBSD supports up to 4 such levels of extraction. If a level was not restored when handling the same HID element, it results in an access to an incorrect memory area. The issue has been resolved in updates FreeBSD 11.3-RELEASE-p10 and 12.1-RELEASE-p6. As a workaround, it is recommended to set the parameter «sysctl hw.usb.disable_enumeration=1».<\/p>\n
