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-2019-18680
https://notcve.org/view.php?id=CVE-2019-18680
An issue was discovered in the Linux kernel 4.4.x before 4.4.195. There is a NULL pointer dereference in rds_tcp_kill_sock() in net/rds/tcp.c that will cause denial of service, aka CID-91573ae4aed0. Se detectó un problema en el kernel de Linux versiones 4.4.x anteriores a 4.4.195. Se presenta una desreferencia del puntero NULL en la función rds_tcp_kill_sock() en el archivo net/rds/tcp.c que causará una denegación de servicio, también se conoce como CID-91573ae4aed0. • https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.4.195 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=91573ae4aed0a49660abdad4d42f2a0db995ee5e https://github.com/torvalds/linux/commit/91573ae4aed0a49660abdad4d42f2a0db995ee5e https://lkml.org/lkml/2019/9/18/337 https://security.netapp.com/advisory/ntap-20191205-0001 • CWE-476: NULL Pointer Dereference •
CVE-2019-17666 – kernel: rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel lacks a certain upper-bound check, leading to a buffer overflow
https://notcve.org/view.php?id=CVE-2019-17666
rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow. En la función rtl_p2p_noa_ie en el archivo drivers/net/wireless/realtek/rtlwifi/ps.c en el kernel de Linux versiones hasta 5.3.6, carece de una cierta comprobación de límite superior, lo que conlleva a un desbordamiento del búfer. A flaw was found in the Linux kernel's implementation of the RealTek wireless drivers WiFi-direct (or WiFi peer-to-peer) driver implementation. When the RealTek wireless networking hardware is configured to accept WiFi-Direct or WiFi P2P connections, an attacker within the wireless network connectivity radio range can exploit a flaw in the WiFi-direct protocol known as "Notice of Absence" by creating specially crafted frames which can then corrupt kernel memory as the upper bounds on the length of the frame is unchecked and supplied by the incoming packet. • https://github.com/uthrasri/CVE-2019-17666 http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00010.html https://access.redhat.com/errata/RHSA-2020:0328 https://access.redhat.com/errata/RHSA-2020:0339 https://access.redhat.com/errata/RHSA-2020:0543 https://access.redhat.com/errata/RHSA-2020:0661 https://access.redhat.com/errata/RHSA-2020:0740 https://arstechnica.com/information-technology/2019/10 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2019-17351
https://notcve.org/view.php?id=CVE-2019-17351
An issue was discovered in drivers/xen/balloon.c in the Linux kernel before 5.2.3, as used in Xen through 4.12.x, allowing guest OS users to cause a denial of service because of unrestricted resource consumption during the mapping of guest memory, aka CID-6ef36ab967c7. Se detectó un problema en el archivo drivers/xen/balloon.c en el kernel de Linux versiones anteriores a 5.2.3, como es usado en Xen versiones hasta 4.12.x, permitiendo a usuarios del sistema operativo invitado causar una denegación de servicio debido al consumo de recursos sin restricciones durante la asignación de la memoria de invitado , también se conoce como CID-6ef36ab967c7. • http://www.openwall.com/lists/oss-security/2019/10/25/9 http://xenbits.xen.org/xsa/advisory-300.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.2.3 https://github.com/torvalds/linux/commit/6ef36ab967c71690ebe7e5ef997a8be4da3bc844 https://security.netapp.com/advisory/ntap-20191031-0005 https://usn.ubuntu.com/4286-1 https://usn.ubuntu.com/4286-2 https://xenbits.xen.org/xsa/advisory-300.html • CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2019-17133 – kernel: buffer overflow in cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c
https://notcve.org/view.php?id=CVE-2019-17133
In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow. En el kernel de Linux versiones hasta 5.3.2, la función cfg80211_mgd_wext_giwessid en el archivo net/wireless/wext-sme.c no rechaza un SSID IE largo, conllevando a un Desbordamiento de Búfer. A vulnerability was found in the Linux kernel's generic WiFi ESSID handling implementation. The flaw allows a system to join a wireless network where the ESSID is longer than the maximum length of 32 characters, which can cause the system to crash or execute code. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00010.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0374 https://access.redhat.com/errata/RHSA-2020:0375 https://access.redhat.com/errata/RHSA-2020:0543 https://access.redhat.com/errata/RHSA-2020:0592 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
