Description
In the Linux kernel, the following vulnerability has been resolved: usb: phy: phy-tahvo: fix memory leak in tahvo_usb_probe() Smatch reports: drivers/usb/phy/phy-tahvo.c: tahvo_usb_probe() warn: missing unwind goto? After geting irq, if ret < 0, it will return without error handling to free memory. Just add error handling to fix this problem.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's usb phy-tahvo driver, specifically in the tahvo_usb_probe() function. When an interrupt request (irq) is obtained and an error occurs (ret < 0), the function returns without properly freeing allocated memory, leading to a memory leak. The fix involves adding error handling to ensure memory is freed in such cases.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing instability in systems using the affected usb phy-tahvo driver.

Mitigation Strategies

Apply the updated Linux kernel patch that fixes the memory leak in the tahvo_usb_probe() function by adding proper error handling after the irq acquisition fails. Until the patch is applied, avoid using affected USB PHY devices that rely on the phy-tahvo driver to prevent potential memory leaks.
