AI-Generated

The vulnerability in the Linux kernel affects the memory block device management, specifically in the functions memblk_nr_poison_inc() and memblk_nr_poison_sub(), which improperly handle memory block references, leading to a reference leak. This could potentially exhaust system resources over time, impacting system stability and performance. Linux system administrators and developers should prioritize this issue to ensure efficient memory management and prevent resource depletion.

Original NVD Description

In the Linux kernel, the following vulnerability has been resolved: drivers/base/memory: fix memory block reference leak in poison accounting memblk_nr_poison_inc() and memblk_nr_poison_sub() look up a memory block via find_memory_block_by_id(), which acquires a reference to the memory block device. Both helpers use the returned memory block without dropping that reference, leaking the device reference on each successful lookup. Drop the reference after updating nr_hwpoison.
