Overview

About vulnerability

In the Linux kernel, the following vulnerability has been resolved: iio: accel: adxl380: Avoid reading more entries than present in FIFO The interrupt handler reads FIFO entries in batches of N samples, where N is the number of scan elements that have been enabled. However, the sensor fills the FIFO one sample at a time, even when more than one channel is enabled. Therefore,the number of entries reported by the FIFO status registers may not be a multiple of N; if this number is not a multiple, the number of entries read from the FIFO may exceed the number of entries actually present. To fix the above issue, round down the number of FIFO entries read from the status registers so that it is always a multiple of N. A flaw was found in the Linux kernel’s iio: accel: adxl380 driver. The driver’s interrupt handler, responsible for reading data from the sensor’s FIFO (First-In, First-Out) buffer, can miscalculate the number of entries. This error may cause the driver to attempt to read beyond the actual data present in the buffer. Such an out-of-bounds read can lead to system instability or a crash, resulting in a Denial of Service (DoS).
