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') •

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') •
CVE-2019-17075
https://notcve.org/view.php?id=CVE-2019-17075
An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable. This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an architecture for which this stack/DMA interaction has security relevance. Se detectó un problema en la función write_tpt_entry en el archivo drivers/infiniband/hw/cxgb4/mem.c en el kernel de Linux versiones hasta 5.3.2. El controlador cxgb4 está llamando directamente a dma_map_single (una función DMA) desde una variable de la pila. • http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lore.kernel.org/lkml/20191001165611.GA3542072%40kroah.com https://seclists.org/bugtraq/2019/Nov/11 https://usn.ubuntu.com/4208-1 https://usn.ubuntu.com/4210-1 https://usn.ubuntu.com/4211-1 https://usn.ubuntu.com/4211-2 https://usn.ubuntu.com/4226-1 https://www.oracle.com/security-alerts/cp •
CVE-2019-17053 – kernel: unprivileged users able to create RAW sockets in AF_IEEE802154 network protocol
https://notcve.org/view.php?id=CVE-2019-17053
ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-e69dbd4619e7. ieee802154_create en net / ieee802154 / socket.c en el módulo de red AF_IEEE802154 en el kernel de Linux hasta la versión 5.3.2 no aplica CAP_NET_RAW, lo que significa que los usuarios no privilegiados pueden crear un socket en bruto, también conocido como CID-e69dbd4619e7. A vulnerability was discovered in the Linux kernel's AF_IEEE802154 networking module where permissions checks are not enforced. This can allow an unprivileged user to create raw sockets for this protocol leading to the potential for data leaks or system unavailability. • http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0edc3f703f7bcaf550774b5d43ab727bcd0fe06b https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e69dbd4619e7674c1679cba49afd9dd9ac347eef https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lists.fedoraproject.org/archives • CWE-250: Execution with Unnecessary Privileges CWE-276: Incorrect Default Permissions •
