Description

A flaw was found in the vdpa_sim component of the Linux kernel. This memory leak vulnerability occurs when a module is probed and the device_register() function fails within vdpasim_net_init() or vdpasim_blk_init(). In such a scenario, the reference count of the kobject is not properly decreased, leading to the leakage of the allocated device name. A local attacker could exploit this flaw to cause a denial of service (DoS) due to resource exhaustion.
