https://notcve.org/view.php?id=CVE-2019-19537
In the Linux kernel before 5.2.10, there is a race condition bug that can be caused by a malicious USB device in the USB character device driver layer, aka CID-303911cfc5b9. This affects drivers/usb/core/file.c. En el kernel de Linux versiones anteriores a 5.2.10, se presenta un bug de condición de carrera que puede ser causado por un dispositivo USB malicioso en la capa del controlador del dispositivo de caracteres USB, también se conoce como CID-303911cfc5b9. Esto afecta al archivo drivers/usb/core/file.c. A flaw was found in the Linux kernel, where there is a race condition bug that can be caused by a malicious USB device in the USB character device driver layer. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html http://www.openwall.com/lists/oss-security/2019/12/03/4 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.2.10 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=303911cfc5b95d33687d9046133ff184cf5043ff https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://access.redhat.com/security/cve& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

relay_open in kernel/relay.c in the Linux kernel through 5.4.1 allows local users to cause a denial of service (such as relay blockage) by triggering a NULL alloc_percpu result. La función relay_open en el archivo kernel/relay.c en el kernel de Linux versiones hasta 5.4.1, permite a usuarios locales causar una denegación de servicio (tal y como un bloqueo de retransmisión) al desencadenar un resultado NULL de alloc_percpu. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00008.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lore.kernel.org/lkml/20191129013745.7168-1-dja%40axtens.net https://security.netapp.com/advisory/ntap-20210129-0004 https://syzkaller-ppc64.appspot.com/bug?id=1c09906c83a8ea811a9e318c2a4f8e243becc6f8 https://syzkaller-ppc64.appspot.com/bug?id=b05b4d005191cc375cdf848c3d4d980308d50531 https://syzkaller&# • CWE-476: NULL Pointer Dereference •

In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and unmounting can lead to a use-after-free in btrfs_queue_work in fs/btrfs/async-thread.c. En el kernel de Linux versión 5.0.21, montar una imagen de sistema de archivos btrfs diseñada, realizar algunas operaciones y desmontarlas puede conllevar a un uso de la memoria previamente liberada en la función btrfs_queue_work en el archivo fs/btrfs/async-thread.c. • https://github.com/bobfuzzer/CVE/tree/master/CVE-2019-19377 https://lists.debian.org/debian-lts-announce/2020/12/msg00015.html https://security.netapp.com/advisory/ntap-20200103-0001 https://usn.ubuntu.com/4367-1 https://usn.ubuntu.com/4369-1 https://usn.ubuntu.com/4414-1 • CWE-416: Use After Free •

A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA. Se encontró un desbordamiento de búfer en la región stack de la memoria en el kernel de Linux, versión kernel-2.6.32, en el controlador del chip WiFi de Marvell. Un atacante es capaz de causar una denegación de servicio (bloqueo del sistema) o, posiblemente, ejecutar código arbitrario, cuando una STA funciona en modo IBSS (permite conectar estaciones juntas sin el uso de un AP) y se conecta a otra STA. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html http://packetstormsecurity.com/files/155879/Kernel-Live-Patch-Security-Notice-LSN-0061-1.html http://packetstormsecurity.com/files/156185/Kernel-Live-Patch-Security-Notice-LSN-0062-1.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14897 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/list& • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 4.7EPSS: 0%CPEs: 12EXPL: 0CVE-2019-18660 – kernel: powerpc: incomplete Spectre-RSB mitigation leads to information exposure
https://notcve.org/view.php?id=CVE-2019-18660
The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. El kernel de Linux anterior a la versión 5.4.1 en powerpc permite la exposición de información porque la mitigación Spectre-RSB no está implementada para todas las CPU aplicables, también conocido como CID-39e72bf96f58. Esto está relacionado con arch / powerpc / kernel / entry_64.S y arch / powerpc / kernel / security.c. A flaw was found in the way the Linux kernel implemented a software flush of the Count Cache (indirect branch cache) and Link (Return Address) Stack on the PowerPC platform. • 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 http://www.openwall.com/lists/oss-security/2019/11/27/1 https://access.redhat.com/errata/RHSA-2020:0174 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=39e72bf96f5847ba87cc5bd7a3ce0fed813dc9ad https://lists.fedoraproject.org& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
