CVE-2026-23325
Description
A flaw was found in the Linux kernel's mt76 WiFi driver, specifically within the mt7996 component. This vulnerability, an out-of-bounds (OOB) access, occurs because the driver does not adequately check the length of incoming data frames before attempting to read or write to memory. A local attacker could exploit this weakness to trigger memory corruption, which may lead to a system crash (Denial of Service) or other unpredictable system behavior.
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.
