https://notcve.org/view.php?id=CVE-2019-19966
In the Linux kernel before 5.1.6, there is a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service, aka CID-dea37a972655. En el kernel de Linux versiones anteriores a 5.1.6, se presenta un uso de la memoria previamente liberada de la función cpia2_exit() en el archivo drivers/media/usb/cpia2/cpia2_v4l.c que causará una denegación de servicio, también se conoce como CID-dea37a972655. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.1.6 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dea37a97265588da604c6ba80160a287b72c7bfd https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://security.netapp.com/advisory/ntap-20200204-0002 • CWE-416: Use After Free •
CVE-2019-19947
https://notcve.org/view.php?id=CVE-2019-19947
In the Linux kernel through 5.4.6, there are information leaks of uninitialized memory to a USB device in the drivers/net/can/usb/kvaser_usb/kvaser_usb_leaf.c driver, aka CID-da2311a6385c. En el kernel de Linux versiones hasta 5.4.6, se presenta un filtrado de información de la memoria no inicializada hacia un dispositivo USB en el archivo controlador drivers/net/can/usb/kvaser_usb/kvaser_usb_leaf.c, también se conoce como CID-da2311a6385c. • http://www.openwall.com/lists/oss-security/2019/12/24/1 https://github.com/torvalds/linux/commit/da2311a6385c3b499da2ed5d9be59ce331fa93e9 https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://security.netapp.com/advisory/ntap-20200204-0002 https://usn.ubuntu.com/4284-1 https://usn.ubuntu.com/4285-1 https://usn.ubuntu.com/4427-1 https://usn.ubuntu.com/4485-1 • CWE-908: Use of Uninitialized Resource •
CVE-2019-19922 – kernel: when cpu.cfs_quota_us is used allows attackers to cause a denial of service against non-cpu-bound applications
https://notcve.org/view.php?id=CVE-2019-19922
kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words, although this slice expiration would typically be seen with benign workloads, it is possible that an attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray requests. An attack does not affect the stability of the kernel; it only causes mismanagement of application execution.) El archivo kernel/sched/fair.c en el kernel de Linux versiones anteriores a 5.3.9, cuando la función cpu.cfs_quota_us es usada (por ejemplo, con Kubernetes), permite a atacantes causar una denegación de servicio contra aplicaciones no vinculadas a la CPU al generar una carga de trabajo que desencadena vencimiento de corte no deseado, también se conoce como CID-de53fd7aedb1. (En otras palabras, aunque esta caducidad de corte se vería típicamente con cargas de trabajo benignas, es posible que un atacante pueda calcular cuántas peticiones extraviadas se requieren para forzar a un clúster Kubernetes completo a un estado de bajo rendimiento causado por la caducidad de corte, y garantizar que un ataque DDoS envió esa cantidad de peticiones perdidas. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.9 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=de53fd7aedb100f03e5d2231cfce0e4993282425 https://github.com/kubernetes/kubernetes/issues/67577 https://github.com/torvalds/linux/commit/de53fd7aedb100f03e5d2231cfce0e4993282425 https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://relistan.com/the-kernel-may-be-slowing-down-your-app https://security.netapp.com/advisory/ntap-20200204-0002 https:/& • CWE-400: Uncontrolled Resource Consumption •
CVE-2019-19447 – kernel: mounting a crafted ext4 filesystem image, performing some operations, and unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c
https://notcve.org/view.php?id=CVE-2019-19447
In the Linux kernel 5.0.21, mounting a crafted ext4 filesystem image, performing some operations, and unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list in fs/ext4/super.c. En el kernel de Linux versión 5.0.21, montando una imagen de sistema de archivos ext4 diseñada, al realizar algunas operaciones y desmontarla puede conllevar a un uso de la memoria previamente liberada en la función ext4_put_super en el archivo fs/ext4/super.c, relacionado con la función dump_orphan_list en el archivo fs/ext4/super.do. A flaw was found in the Linux kernel's ext4_unlink function. An attacker could corrupt memory or escalate privileges when deleting a file from a recently unmounted specially crafted ext4 filesystem, including local, USB, and iSCSI. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html https://github.com/bobfuzzer/CVE/tree/master/CVE-2019-19447 https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://security.netapp.com/advisory/ntap-20200103-0001 https://access.redhat.com/security/cve/CVE-2019-19447 https://bugzilla.redhat.com/show_bug.cgi • CWE-416: Use After Free •
CVE-2019-19063 – kernel: Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c allow for a DoS
https://notcve.org/view.php?id=CVE-2019-19063
Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption), aka CID-3f9361695113. Dos pérdidas de memoria en la función rtl_usb_probe() en el archivo drivers/net/wireless/realtek/rtlwifi/usb.c en el kernel de Linux versiones hasta la versión 5.3.11, permiten a atacantes causar una denegación de servicio (consumo de memoria), también se conoce como CID-3f9361695113. A flaw was found in the Linux kernel. The rtl_usb_probe function mishandles resource cleanup on error. An attacker able to induce the error conditions could use this flaw to crash the system. • 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 https://github.com/torvalds/linux/commit/3f93616951138a598d930dcaec40f2bfd9ce43bb https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/O3PSDE6PTOTVBK2YTKB2TFQP2SUBVSNF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PY7LJMSPAGRIKABJPDKQDTXYW3L5RX2T https://seclists.org/bugtraq/2020/Jan • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
