CVE-2026-43307
Description
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).
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
