CVE-2026-31768
Description
A flaw was found in the Linux kernel, specifically within the ti-adc161s626 Analog-to-Digital Converter (ADC) driver. This vulnerability arises from the use of non-Direct Memory Access (DMA)-safe stack memory for Serial Peripheral Interface (SPI) read operations. An attacker with local access could potentially exploit this to cause memory corruption, leading to a denial of service or information disclosure.
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of the product'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 product into an infinite loop.
