Memory Leak in Linux Kernel USB Driver Affects Multiple Releases

CVE-2023-53379

What is CVE-2023-53379?

A vulnerability in the Linux kernel's USB driver, specifically within the phy-tahvo component, has been identified. During the execution of the tahvo_usb_probe() function, an error handling oversight can lead to a memory leak if an interrupt request (IRQ) fails. In this scenario, the function returns without properly freeing allocated memory, which could cause system resource depletion over time. To mitigate this issue, proper error handling has been introduced to ensure that memory is freed appropriately in the event of a failure.
