CVSS: 4.0EPSS: 0%CPEs: 12EXPL: 0CVE-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 •

CVSS: 4.7EPSS: 0%CPEs: 3EXPL: 1CVE-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 •

In the Linux kernel before 4.17, hns_roce_alloc_ucontext in drivers/infiniband/hw/hns/hns_roce_main.c does not initialize the resp data structure, which might allow attackers to obtain sensitive information from kernel stack memory, aka CID-df7e40425813. En el kernel de Linux versiones anteriores a 4.17, la función hns_roce_alloc_ucontext en el archivo drivers/infiniband/hw/hns/hns_roce_main.c no inicializa la estructura de datos resp, lo que podría permitir a atacantes obtener información confidencial de la memoria de la pila del kernel, también se conoce como CID-df7e40425813. • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=df7e40425813c50cd252e6f5e348a81ef1acae56 https://github.com/torvalds/linux/commit/df7e40425813c50cd252e6f5e348a81ef1acae56 • CWE-665: Improper Initialization •
