CVE-2019-18805 – kernel: integer overflow in tcp_ack_update_rtt in net/ipv4/tcp_input.c
https://notcve.org/view.php?id=CVE-2019-18805
An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6. Se detectó un problema en el archivo net/ipv4/sysctl_net_ipv4.c en el kernel de Linux versiones anteriores a 5.0.11. Se presenta un desbordamiento de enteros firmado del archivo net/ipv4/tcp_input.c en la función tcp_ack_update_rtt() cuando el espacio de usuario escribe un entero muy grande en /proc/sys/net/ipv4/tcp_min_rtt_wlen, lo que conlleva a una denegación de servicio o posiblemente a otro impacto no especificado, también se conoce como CID -19fad20d15a6. A flaw was reported in the Linux kernel's TCP subsystem while calculating a packet round trip time, when a sysctl parameter (/proc/sys/net/ipv4/tcp_min_rtt_wlen) is set incorrectly. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00039.html https://access.redhat.com/errata/RHSA-2020:0740 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.11 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=19fad20d15a6494f47f85d869f00b11343ee5c78 https://security.netapp.com/advisory/ntap-20191205-0001 https://access.redhat.com/security/cve/CVE-2019-18805 https: • CWE-190: Integer Overflow or Wraparound •
CVE-2019-18683
https://notcve.org/view.php?id=CVE-2019-18683
An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free. • https://github.com/sanjana123-cloud/CVE-2019-18683 http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://packetstormsecurity.com/files/155890/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/11/05/1 https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lore.kernel.org/lkml/20191103221719.27118-1-alex.popov%40linux.com https://seclists.org/bugtraq/2020/Jan/10 https://security.net • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVE-2019-2215 – Android Kernel Use-After-Free Vulnerability
https://notcve.org/view.php?id=CVE-2019-2215
A use-after-free in binder.c allows an elevation of privilege from an application to the Linux Kernel. No user interaction is required to exploit this vulnerability, however exploitation does require either the installation of a malicious local application or a separate vulnerability in a network facing application.Product: AndroidAndroid ID: A-141720095 Un uso de la memoria previamente liberada en el archivo binder.c, permite una elevación de privilegios desde una aplicación en el kernel de Linux. No es requerida una interacción del usuario para explotar esta vulnerabilidad, sin embargo, la explotación necesita de la instalación de una aplicación local maliciosa o una vulnerabilidad separada en una aplicación de red.

CVE-2019-16995
https://notcve.org/view.php?id=CVE-2019-16995
In the Linux kernel before 5.0.3, a memory leak exits in hsr_dev_finalize() in net/hsr/hsr_device.c if hsr_add_port fails to add a port, which may cause denial of service, aka CID-6caabe7f197d. En el kernel de Linux versiones anterior a 5.0.3, se presenta una pérdida de memoria en la función hsr_dev_finalize() en el archivo net/hsr/hsr_device.c si hsr_add_port no puede agregar un puerto, lo que puede causar una denegación de servicio, también se conoce como CID-6caabe7f197d. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00035.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.3 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6caabe7f197d3466d238f70915d65301f1716626 https://github.com/torvalds/linux/commit/6caabe7f197d3466d238f70915d65301f1716626 https://security.netapp.com/advisory/ntap-20191031-0005 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2019-14814 – kernel: heap overflow in mwifiex_set_uap_rates() function of Marvell Wifi Driver leading to DoS
https://notcve.org/view.php?id=CVE-2019-14814
There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. Se presenta un desbordamiento de búfer en la región heap de la memoria en el kernel de Linux, todas las versiones hasta 5.3 (excluyéndola), en el controlador de chip wifi marvell en el kernel de Linux, que permite a usuarios locales causar una denegación de servicio (bloqueo del sistema) o posiblemente ejecutar código arbitrario. A flaw was found in the Linux kernel’s implementation of the Marvell wifi driver, which can allow a local user who has CAP_NET_ADMIN or administrative privileges to possibly cause a Denial Of Service (DOS) by corrupting memory and possible code execution. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/08/28/1 https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0328 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
