CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2019-18811 – kernel: memory leak in sof_set_get_large_ctrl_data() function in sound/soc/sof/ipc.c
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 •

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 •

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') •

An issue was discovered in Xen through 4.12.x allowing ARM guest OS users to cause a denial of service via a XENMEM_add_to_physmap hypercall. p2m->max_mapped_gfn is used by the functions p2m_resolve_translation_fault() and p2m_get_entry() to sanity check guest physical frame. The rest of the code in the two functions will assume that there is a valid root table and check that with BUG_ON(). The function p2m_get_root_pointer() will ignore the unused top bits of a guest physical frame. This means that the function p2m_set_entry() will alias the frame. However, p2m->max_mapped_gfn will be updated using the original frame. • http://www.openwall.com/lists/oss-security/2019/10/31/4 http://xenbits.xen.org/xsa/advisory-301.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/IZYATWNUGHRBG6I3TC24YHP5Y3J7I6KH https://seclists.org/bugtraq/2020/Jan/21 https:// • CWE-193: Off-by-one Error •
