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 •

An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check the length of variable elements in a beacon head, leading to a buffer overflow. Se detectó un problema en el archivo net/wireless/nl80211.c en el kernel de Linux versiones hasta 5.2.17. No comprueba la longitud de los elementos variables en un beacon head, lo que provoca un desbordamiento del búfer.

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 •
