Local Variable Vulnerability in Hisilicon hibmc Driver for Linux Kernel

CVE-2025-39785

What is CVE-2025-39785?

A use-after-free vulnerability has been identified in the Hisilicon hibmc driver within the Linux Kernel. This vulnerability arises from the improper handling of a local variable in the irq_request() function, leading to potential failures when calling request_irq(). The issue is resolved by utilizing a global irq name, thereby preventing the local variable from being passed erroneously. This fix addresses the risk associated with the use of freed memory, enhancing the stability and security of the Linux Kernel.
