CVE-2026-23557

Any guest can cause xenstored to crash by issuing a XSRESETWATCHES command within a transaction due to an assert triggering. In case xenstored was built with NDEBUG defined nothing bad will happen, as assert is doing nothing in this case. Note that the default is not to define NDEBUG for xenstore...

NULL Pointer Dereference

xen is vulnerable to NULL Pointer Dereference. The vulnerability is due to the incorrect assumption in C Xenstored that the quota cannot be negative. This leads to a crash when accounting temporarily goes negative, as assert checks fail when tools are built with default settings, which do not...

Design/Logic Flaw

Crypto++ aka cryptopp through 5.6.4 does not document the requirement for a compile-time NDEBUG definition disabling the many assert calls that are unintended in production use, which might allow context-dependent attackers to obtain sensitive information by leveraging access to process memory...
