25 Dec 2019 — 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 • CWE-416: Use After Free •

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 • CWE-908: Use of Uninitialized Resource •
CVSS: 7.4EPSS: 0%CPEs: 24EXPL: 1CVE-2019-5108 – kernel: triggering AP to send IAPP location updates for stations before the required authentication process has completed can lead to DoS
https://notcve.org/view.php?id=CVE-2019-5108
23 Dec 2019 — An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentic... • http://packetstormsecurity.com/files/156455/Kernel-Live-Patch-Security-Notice-LSN-0063-1.html • CWE-287: Improper Authentication CWE-440: Expected Behavior Violation •
CVSS: 5.5EPSS: 0%CPEs: 15EXPL: 1CVE-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
22 Dec 2019 — 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-perfo... • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.9 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2019-19241
16 Dec 2019 — In the Linux kernel before 5.4.2, the io_uring feature leads to requests that inadvertently have UID 0 and full capabilities, aka CID-181e448d8709. This is related to fs/io-wq.c, fs/io_uring.c, and net/socket.c. For example, an attacker can bypass intended restrictions on adding an IPv4 address to the loopback interface. This occurs because IORING_OP_SENDMSG operations, although requested in the context of an unprivileged user, are sometimes performed by a kernel worker thread without considering that conte... • https://www.exploit-db.com/exploits/47779 •
