CVE-2019-18809 – kernel: memory leak in af9005_identify_state() function in drivers/media/usb/dvb-usb/af9005.c
https://notcve.org/view.php?id=CVE-2019-18809
A memory leak in the af9005_identify_state() function in drivers/media/usb/dvb-usb/af9005.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-2289adbfa559. Una pérdida de memoria en la función af9005_identify_state() en el archivo drivers/media/usb/dvb-usb/af9005.c en el kernel de Linux versiones hasta 5.3.9, permite a atacantes causar una denegación de servicio (consumo de memoria), también se conoce como CID-2289adbfa559. A flaw was found in the Afatech 9005 DVB-T receiver driver in the Linux kernel. An attacker, with physical access to the system, could cause the system to crash following a resource cleanup. The highest threat from this vulnerability is to system availability. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html https://github.com/torvalds/linux/commit/2289adbfa559050d2a38bcd9caac1c18b800e928 https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LYIFGYEDQXP5DVJQQUARQRK2PXKBKQGY https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YWWOOJKZ4NQYN4RMFIVJ3ZIXKJJI3MKP https://security.netapp.com/advisory/ntap-20191205-0001 https://usn • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2019-18811
A memory leak in the sof_set_get_large_ctrl_data() function in sound/soc/sof/ipc.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering sof_get_ctrl_copy_params() failures, aka CID-45c1380358b1. Una pérdida de memoria en la función sof_set_get_large_ctrl_data() en el archivo sound/soc/sof/ipc.c en el kernel de Linux versiones hasta 5.3.9, permite a atacantes causar una denegación de servicio (consumo de memoria) mediante la activación de fallos de la función sof_get_ctrl_copy_params(), también se conoce como CID-45c1380358b1. A flaw was found in the Linux kernel’s sof_set_get_large_ctrl_data function, in the way it handled memory cleanup in a specific error path. A local attacker could use this flaw to crash the system. • https://github.com/torvalds/linux/commit/45c1380358b12bf2d1db20a5874e9544f56b34ab https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LYIFGYEDQXP5DVJQQUARQRK2PXKBKQGY https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YWWOOJKZ4NQYN4RMFIVJ3ZIXKJJI3MKP https://security.netapp.com/advisory/ntap-20191205-0001 https://usn.ubuntu.com/4284-1 https://access.redhat.com/security/cve/CVE-2019-18811 https://bugzilla.redhat.com/show_bug.cgi?id=1777455 • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •

CVE-2019-18425
https://notcve.org/view.php?id=CVE-2019-18425
An issue was discovered in Xen through 4.12.x allowing 32-bit PV guest OS users to gain guest OS privileges by installing and using descriptors. There is missing descriptor table limit checking in x86 PV emulation. When emulating certain PV guest operations, descriptor table accesses are performed by the emulating code. Such accesses should respect the guest specified limits, unless otherwise guaranteed to fail in such a case. Without this, emulation of 32-bit guest user mode calls through call gates would allow guest user mode to install and then use descriptors of their choice, as long as the guest kernel did not itself install an LDT. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00037.html http://www.openwall.com/lists/oss-security/2019/10/31/2 http://xenbits.xen.org/xsa/advisory-298.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2BQKX7M2RHCWDBKNPX4KEBI3MJIH6AYZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I5WWPW4BSZDDW7VHU427XTVXV7ROOFFW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IZYATWNUG • CWE-269: Improper Privilege Management •
CVE-2019-18424
https://notcve.org/view.php?id=CVE-2019-18424
An issue was discovered in Xen through 4.12.x allowing attackers to gain host OS privileges via DMA in a situation where an untrusted domain has access to a physical device. This occurs because passed through PCI devices may corrupt host memory after deassignment. When a PCI device is assigned to an untrusted domain, it is possible for that domain to program the device to DMA to an arbitrary address. The IOMMU is used to protect the host from malicious DMA by making sure that the device addresses can only target memory assigned to the guest. However, when the guest domain is torn down, or the device is deassigned, the device is assigned back to dom0, thus allowing any in-flight DMA to potentially target critical host data. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00037.html http://www.openwall.com/lists/oss-security/2019/10/31/6 http://xenbits.xen.org/xsa/advisory-302.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2BQKX7M2RHCWDBKNPX4KEBI3MJIH6AYZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I5WWPW4BSZDDW7VHU427XTVXV7ROOFFW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IZYATWNUG • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
