Local Interrupt Management Vulnerability in Linux Kernel Affecting Multiple Releases

CVE-2026-98832

What is CVE-2026-98832?

A local interrupt management issue has been identified in the Linux kernel where the improper handling of interrupt states while holding locks could lead to potential deadlocks. The problem arises when the function bio_set_dev() is called with interrupts disabled while another process can trigger a softirq, resulting in re-acquiring the lock and causing inconsistency in the interrupt management within the kernel. This flaw highlights the necessity for careful management of interrupt states and locking mechanisms to prevent potential system stalls.
