CVE-2024-57910

HIGH

Linux Kernel 5.4.132-5.4.290 - Information Disclosure via Uninitialized Buffer in vcnl4035 Light Sensor Driver

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: iio: light: vcnl4035: fix information leak in triggered buffer The 'buffer' local array is used to push data to userspace from a triggered buffer, but it does not set an initial value for the single data element, which is an u16 aligned to 8 bytes. That leaves at least 4 bytes uninitialized even after writing an integer value with regmap_read(). Initialize the array to zero before using it to avoid pushing uninitialized information to userspace.
