CVE-2022-49883 is an out-of-bounds read vulnerability in the Linux kernel's KVM subsystem, specifically affecting 64-bit hosts when a guest operating system lacks the X86_FEATURE_LM. This flaw allows KVM to attempt accessing 16 General Purpose Registers (GPRs) within a 32-bit SMRAM image, leading to an out-of-bounds memory access. With a CVSS score of 7.1 (HIGH), successful exploitation could result in high confidentiality impact and high availability impact, though it requires local access and low attack complexity. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
