https://notcve.org/view.php?id=CVE-2023-1544
A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to allocate and initialize a huge number of page tables to be used as a ring of descriptors for CQ and async events, potentially leading to an out-of-bounds read and crash of QEMU. • https://access.redhat.com/security/cve/CVE-2023-1544 https://bugzilla.redhat.com/show_bug.cgi?id=2180364 https://lists.nongnu.org/archive/html/qemu-devel/2023-03/msg00206.html https://security.netapp.com/advisory/ntap-20230511-0005 • CWE-125: Out-of-bounds Read CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 6.5EPSS: 0%CPEs: 4EXPL: 0CVE-2022-4144 – QEMU: QXL: qxl_phys2virt unsafe address translation can lead to out-of-bounds read
https://notcve.org/view.php?id=CVE-2022-4144
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. Se encontró una falla de lectura fuera de los límites en la emulación del dispositivo de visualización QXL en QEMU. La función qxl_phys2virt() no verifica el tamaño de la estructura a la que apunta la dirección física del invitado, lo que potencialmente lee más allá del final del espacio de la barra en páginas adyacentes. • https://bugzilla.redhat.com/show_bug.cgi?id=2148506 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GTVPHLLXJ65BUMFBUUZ35F3J632SLFRK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I7J5IRXJYLELW7D43A75LOWRUE5EU54O https://lists.nongnu.org/archive/html/qemu-devel/2022-11/msg04143.html https://security.netapp.com/advisory/ntap-20230127-0012 https://access.redhat.com/security/cve/CVE-2022-4144 • CWE-125: Out-of-bounds Read •

An off-by-one read/write issue was found in the SDHCI device of QEMU. It occurs when reading/writing the Buffer Data Port Register in sdhci_read_dataport and sdhci_write_dataport, respectively, if data_count == block_size. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.

A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. This flaw allows a malicious privileged user within the guest to crash the QEMU process on the host, resulting in a denial of service. Se ha encontrado una vulnerabilidad de uso de memoria previamente liberada en la emulación del adaptador de bus de host LSI53C895A SCSI de QEMU. El fallo es producido mientras son procesados mensajes repetidos para cancelar la petición SCSI actual por medio de la función lsi_do_msgout. • https://access.redhat.com/security/cve/CVE-2022-0216 https://bugzilla.redhat.com/show_bug.cgi?id=2036953 https://gitlab.com/qemu-project/qemu/-/commit/4367a20cc4 https://gitlab.com/qemu-project/qemu/-/issues/972 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZTY7TVHX62OJWF6IOBCIGLR2N5K4QN3E https://starlabs.sg/advisories/22/22-0216 • CWE-416: Use After Free •
