CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's s390 architecture, specifically within the ism interrupt handling mechanism, where a use-after-free condition can occur during the ism_dev_exit() process. This flaw allows an active interrupt handler to access freed data structures, potentially leading to system instability or exploitation. Organizations utilizing Linux on s390 systems should prioritize addressing this vulnerability to maintain system integrity and security.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: s390/ism: Fix UAF of sba and ieq during ism_dev_exit() A ism interrupt handler can be active in parallel with ism_dev_exit(), accessing freed data structures. No new interrupts will be generated after unregister_ieq(). Drain ongoing interrupt handlers by free_irq(), before freeing ism data structures.
