Description

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: configfs: Prevent OOB read/write in usb_string_copy() Userspace provided string 's' could trivially have the length zero. Left unchecked this will firstly result in an OOB read in the form `if (str[0 - 1] == '\n') followed closely by an OOB write in the form `str[0 - 1] = '\0'`. There is already a validating check to catch strings that are too long. Let's supply an additional check for invalid strings that are too short.

Affected configurations

• linux linux kernel (< 4.19.318) • linux linux kernel (>= 4.20 < 5.4.280) • linux linux kernel (>= 5.5 < 5.10.222) • linux linux kernel (>= 5.11 < 5.15.163) • linux linux kernel (>= 5.16 < 6.1.100) • linux linux kernel (>= 6.2 < 6.6.41) • linux linux kernel (>= 6.7 < 6.9.10)
