CVE-2026-64085
Description
A flaw was found in the Linux kernel's pmbus/adm1266 driver, which is responsible for hardware monitoring. This vulnerability occurs because the driver does not properly handle data sizes when reading blackbox records from a device. A malicious or malformed device could send more data than expected, causing a buffer overflow. This could lead to memory corruption within the kernel, potentially allowing a local attacker to escalate privileges or cause a system crash (Denial of Service).
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.
