Resource Leak in Linux Kernel HSI ssi_protocol Component

Publication date: 2025-12-24

Last updated on: 2025-12-24

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: HSI: ssi_protocol: fix potential resource leak in ssip_pn_open() ssip_pn_open() claims the HSI client's port with hsi_claim_port(). When hsi_register_port_event() gets some error and returns a negetive value, the HSI client's port should be released with hsi_release_port(). Fix it by calling hsi_release_port() when hsi_register_port_event() fails.

Executive Summary

This vulnerability is a potential resource leak in the Linux kernel's HSI subsystem, specifically in the ssip_pn_open() function. When ssip_pn_open() claims a port using hsi_claim_port(), if the subsequent call to hsi_register_port_event() fails (returns a negative value), the claimed port is not released properly. The fix involves ensuring that hsi_release_port() is called to release the port when hsi_register_port_event() fails, preventing the resource leak.

Impact Analysis

This vulnerability can lead to a resource leak in the Linux kernel's HSI subsystem, which may cause system instability or degraded performance over time due to unreleased ports. However, no direct impact such as privilege escalation or data corruption is described.

Mitigation Strategies

Apply the patch or update to the Linux kernel version that includes the fix for the resource leak in ssip_pn_open() by ensuring hsi_release_port() is called when hsi_register_port_event() fails.
