CVE-2010-0298 describes a privilege escalation and denial-of-service vulnerability in the x86 emulator of KVM 83, affecting Debian and Linux kernels. The flaw stems from the emulator's failure to properly enforce CPL and IOPL for memory access, allowing guest OS users to manipulate IO ports or MMIO regions. With a CVSS score of 6.5, this vulnerability has a medium severity, requiring authenticated access (Au:S) but with low attack complexity (AC:L) to achieve partial confidentiality, integrity, and availability impacts. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.

kvm: emulator privilege escalation
Feb 9, 2010The x86 emulator in KVM 83 does not use the Current Privilege Level (CPL) and I/O Privilege Level (IOPL) in determining the memory access available to CPL3 code which allows guest OS users to cause a denial of service (guest OS crash) or gain privileges on the guest OS by leveraging access to a (1) IO port or (2) MMIO region a related issue to CVE-2010-0306.
