CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's HID sensor-hub component, where an out-of-bounds write can occur due to improper handling of feature field sizes in the sensor_hub_get_feature() function. This flaw allows a malicious HID descriptor to exploit a small stack buffer, potentially leading to memory corruption and arbitrary code execution. Organizations using Linux systems, particularly those with HID devices, should prioritize addressing this vulnerability to mitigate risks associated with unauthorized access and system compromise.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: HID: sensor-hub: Fix out-of-bounds write in sensor_hub_get_feature sensor_hub_get_feature() clamps its return value to the caller's buffer size, but the copy loop still copies field->report_size / 8 bytes for each report value. A malicious HID descriptor can advertise a large feature field size while an IIO caller supplies a small stack buffer, such as a single s32, causing an out-of-bounds write. HID core stores parsed report values in __s32 slots and clamps extracted values to 32 bits. Reject feature fields that require more than one slot per value, guard the total byte count calculation, and clamp each per-value copy to the remaining caller buffer.
