Описание
In the Linux kernel, the following vulnerability has been resolved:
i2c: tegra: check msg length in SMBUS block read
For SMBUS block read, do not continue to read if the message length
passed from the device is '0' or greater than the maximum allowed bytes.
A flaw was found in the Linux kernel's i2c Tegra driver. A local attacker with high privileges could exploit this vulnerability by providing a specially crafted SMBUS (System Management Bus) block read message with an invalid length. This could lead to an out-of-bounds read, potentially resulting in information disclosure or a denial of service (DoS) on the system.
Отчет
This vulnerability is rated as Moderate impact because exploitation is restricted to hardware platforms running NVIDIA Tegra SoCs and requires administrative privileges to execute arbitrary I2C bus read requests or physical access via a rogue peripheral. Enterprise environments operating on standard x86_64 or non-Tegra server architectures do not utilize this bus driver and are not exposed. If an invalid message length is supplied during an SMBus block read transaction, an out-of-bounds read occurs, potentially leading to denial of service or the leakage of kernel memory.
