Memory corruption

Xenstore: Guests can crash xenstored Due to a bug in the fix of XSA-115 a malicious guest can cause xenstored to use a wrong pointer during node creation in an error path, resulting in a crash of xenstored or a memory corruption in xenstored causing further damage. Entering the error path can be...

CVE-2022-42321

Xenstore: Guests can crash xenstored via exhausting the stack Xenstored is using recursion for some Xenstore operations e.g. for deleting a sub-tree of Xenstore nodes. With sufficiently deep nesting levels this can result in stack exhaustion on xenstored, leading to a crash of xenstored...
