Title: Linux Kernel KVM 'hvc_console.c' Local Denial of Service Vulnerability
Severity: MODERATE
Description:
The Linux kernel is prone to a local denial-of-service vulnerability that affects the Kernel-based Virtual Machine (KVM). Specifically, this issue is caused by a race condition between the 'hvc_remove()' and 'hvc_close()' functions in the 'drivers/char/hvc_console.c' source code file.
Attackers can exploit this issue to crash the affected computer, denying service to legitimate users.
