CVE-2020-29481 is a high-severity vulnerability affecting Xen through version 4.14.x, including various Debian and Fedora distributions. It allows a newly created guest domain to inherit Xenstore access rights from a previously destroyed domain with the same ID, potentially enabling unauthorized access to sensitive information from other running guests. The vulnerability has a CVSS score of 8.8 (HIGH), indicating a local attack vector with low complexity, requiring low privileges, and resulting in high confidentiality, integrity, and availability impacts. This means an attacker with local access to the Xen hypervisor could potentially read or modify data belonging to other virtual machines. Currently, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal, suggesting it has not garnered significant public attention.
