| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A potential buffer overflow issue exists in the
i2c hid get report() function within the Linux kernel's HID i2c subsystem. The i2c hid xfer function reads data into ihid->rawbuf, and the amount of data read (recv len + sizeof( le16)) can exceed the buffer's capacity if recv len is not properly limited. The vulnerability is addressed by truncating recv len to ihid->bufsize - sizeof( le16). Access to hidraw devices requires root privileges. The function i2c hid xfer is involved in the issue.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
