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 •

atalk_create in net/appletalk/ddp.c in the AF_APPLETALK 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-6cc03e8aa36c. La función atalk_create en el archivo net/appletalk/ddp.c en el módulo de red AF_APPLETALK en el kernel de Linux versiones hasta 5.3.2 no aplica CAP_NET_RAW, lo que significa que los usuarios no privilegiados pueden crear un socket en bruto, también se conoce como CID-6cc03e8aa36c. • 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=6cc03e8aa36c51f3b26a0d21a3c4ce2809c842ac 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-276: Incorrect Default Permissions •
CVE-2019-17055 – kernel: unprivileged users able to create RAW sockets in AF_ISDN network protocol
https://notcve.org/view.php?id=CVE-2019-17055
base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN 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-b91ee4aa2a21. La función base_sock_create en el archivo drivers/isdn/mISDN/socket.c en el módulo de red AF_ISDN en el kernel de Linux versiones hasta 5.3.2 no aplica CAP_NET_RAW, lo que significa que los usuarios no privilegiados pueden crear un socket en bruto, también se conoce como CID-b91ee4aa2a21. A vulnerability was found in the Linux kernel’s implementation of the AF_ISDN protocol, which does not enforce the CAP_NET_RAW capability. This flaw can allow unprivileged users to create a raw socket for this protocol. This could further allow the user to control the availability of an existing ISDN circuit. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00039.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://access.redhat.com/errata/RHSA-2020:0790 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=b91ee4aa2 • CWE-250: Execution with Unnecessary Privileges CWE-862: Missing Authorization •

CVE-2019-16994 – kernel: Memory leak in sit_init_net() in net/ipv6/sit.c
https://notcve.org/view.php?id=CVE-2019-16994
In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka CID-07f12b26e21a. En el kernel de Linux versiones anteriores a 5.0, se presenta una pérdida de memoria en la función sit_init_net() en el archivo net/ipv6/sit.c cuando la función register_netdev() no puede registrar sitn-)fb_tunnel_dev, lo que puede causar una denegación de servicio, también se conoce como CID-07f12b26e21a. A flaw was found in the way the sit_init_net function in the Linux kernel handled resource cleanup on errors. This flaw allows an attacker to use the error conditions to crash the system. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=07f12b26e21ab359261bf75cfcb424fdc7daeb6d https://github.com/torvalds/linux/commit/07f12b26e21ab359261bf75cfcb424fdc7daeb6d https://security.netapp.com/advisory/ntap-20191031-0005 https://access.redhat.com/security/cve/CVE-2019-16994 https://bugzilla.redhat.com/show_bug.cgi?id=1759681 • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
