CVE-2026-23308
Description
A flaw was found in the Linux kernel's pinctrl equilibrium driver. This issue arises from a redundant call to the gpiochip_disable_irq() function within eqbr_irq_mask(). Consequently, the system generates excessive warning traces in the kernel log during system load. While not directly exploitable for arbitrary code execution or privilege escalation, these noisy logs could potentially obscure more critical system messages, impacting system observability.
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Other)
Log files can become so large that they consume excessive resources, such as disk and CPU, which can hinder the performance of the system.
Non-Repudiation
Technical Impact: Hide Activities
Logging too much information can make the log files of less use to forensics analysts and developers when trying to diagnose a problem or recover from an attack.
Non-Repudiation
Technical Impact: Hide Activities
If system administrators are unable to effectively process log files, attempted attacks may go undetected, possibly leading to eventual system compromise.
