Buffer overflow in the ccid_card_vscard_handle_message function in hw/ccid-card-passthru.c in QEMU before 0.15.2 and 1.x before 1.0-rc4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VSC_ATR message.
CVE-2016-7421 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 2.1 LOW 4.4 MEDIUM
The pvscsi_ring_pop_req_descr function in hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging failure to limit process IO loop to the ring size.

CVE-2015-8701 1 Qemu 1 Qemu 2025-04-12 2.1 LOW 6.5 MEDIUM
QEMU (aka Quick Emulator) built with the Rocker switch emulation support is vulnerable to an off-by-one error. It happens while processing transmit (tx) descriptors in 'tx_consume' routine, if a descriptor was to have more than allowed (ROCKER_TX_FRAGS_MAX=16) fragments. A privileged user inside guest could use this flaw to cause memory leakage on the host or crash the QEMU process instance resulting in DoS issue.
