Integer overflow in the emulated_apdu_from_guest function in usb/dev-smartcard-reader.c in Quick Emulator (Qemu), when built with the CCID Card device emulator support, allows local users to cause a denial of service (application crash) via a large Application Protocol Data Units (APDU) unit.
CVE-2022-4172 2 Fedoraproject, Qemu 2 Fedora, Qemu 2025-04-14 N/A 6.5 MEDIUM
An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could use these flaws to crash the QEMU process on the host.
CVE-2022-4144 3 Fedoraproject, Qemu, Redhat 4 Extra Packages For Enterprise Linux, Fedora, Qemu and 1 more 2025-04-14 N/A 6.5 MEDIUM
An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition.
