Description Wolfgang Frisch 2020-06-02 09:33:50 UTC

CVE-2020-13659

A NULL pointer dereference issue was found in the MegaRAID SAS 8708EM2 emulator of QEMU. This issue occurs because the address_space_map() API while mapping physical memory into host's virtual address space may return NULL, without setting the length parameter to zero(0). A guest user/process may use this flaw to crash the QEMU process on the host resulting in DoS scenario.
