Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: spi: mpc52xx: fix use-after-free on unbind The state machine work is scheduled by the interrupt handler and therefore needs to be cancelled after disabling interrupts to avoid a potential use-after-free.

CWE ID Description
CWE-416 The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Impact Analysis

The use-after-free vulnerability can potentially lead to system instability, crashes, or exploitation by attackers to execute arbitrary code or cause denial of service by manipulating kernel memory.

Executive Summary

This vulnerability is a use-after-free issue in the Linux kernel's spi: mpc52xx driver. It occurs because the state machine work is scheduled by the interrupt handler and is not properly cancelled after disabling interrupts, which can lead to accessing memory that has already been freed.
