CVE-2026-43355
Description
A flaw was found in the Linux kernel's bh1780 light sensor driver. This vulnerability occurs due to a Power Management (PM) runtime leak, where the system's reference count for power management is not always properly decremented. An attacker could exploit this by repeatedly triggering the error path, leading to resource exhaustion. This can result in a Denial of Service (DoS), making the system unresponsive or unstable.
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
If an adversary can prevent a reference count from reaching zero, then resources might not be released when they are supposed to, thus causing resources to become scarce for future needs.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
If an adversary can cause a reference count to reach zero when the resource is still in use, then a resource might be released before it is supposed to be, possibly forcing an error that causes the product to crash or exit out of its current operation.
