https://notcve.org/view.php?id=CVE-2019-19966
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 •

23 Dec 2019 — 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 • CWE-908: Use of Uninitialized Resource •
CVE-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 •
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
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 •
CVE-2019-19815
https://notcve.org/view.php?id=CVE-2019-19815
17 Dec 2019 — In the Linux kernel 5.0.21, mounting a crafted f2fs filesystem image can cause a NULL pointer dereference in f2fs_recover_fsync_data in fs/f2fs/recovery.c. This is related to F2FS_P_SB in fs/f2fs/f2fs.h. En el kernel de Linux versión 5.0.21, montar una imagen del sistema de archivos f2fs especialmente diseñada puede causar una desreferencia del puntero NULL en la función f2fs_recover_fsync_data en el archivo fs/f2fs/recovery.c. Esto está relacionado con la función F2FS_P_SB en el archivo fs/f2fs/f2fs.h. • https://github.com/bobfuzzer/CVE/tree/master/CVE-2019-19815 • CWE-476: NULL Pointer Dereference •

CVE-2019-19813
https://notcve.org/view.php?id=CVE-2019-19813
17 Dec 2019 — In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in __mutex_lock in kernel/locking/mutex.c. This is related to mutex_can_spin_on_owner in kernel/locking/mutex.c, __btrfs_qgroup_free_meta in fs/btrfs/qgroup.c, and btrfs_insert_delayed_items in fs/btrfs/delayed-inode.c.

17 Dec 2019 — In the Linux kernel 5.0.21, mounting a crafted f2fs filesystem image can cause __remove_dirty_segment slab-out-of-bounds write access because an array is bounded by the number of dirty types (8) but the array index can exceed this. En el kernel de Linux versión 5.0.21, montar una imagen del sistema de archivos f2fs especialmente diseñada puede causar un acceso de escritura fuera de límites en la función __remove_dirty_segment porque una matriz está limitada por parte del número de tipos sucios (8) pero el í... • https://github.com/bobfuzzer/CVE/tree/master/CVE-2019-19814 • CWE-787: Out-of-bounds Write •
CVE-2019-19241 – Linux 5.3 - Privilege Escalation via io_uring Offload of sendmsg() onto Kernel Thread with Kernel Creds
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 •
CVE-2019-19807 – kernel: use-after-free in sound/core/timer.c
https://notcve.org/view.php?id=CVE-2019-19807
15 Dec 2019 — In the Linux kernel before 5.3.11, sound/core/timer.c has a use-after-free caused by erroneous code refactoring, aka CID-e7af6307a8a5. This is related to snd_timer_open and snd_timer_close_locked. The timeri variable was originally intended to be for a newly created timer instance, but was used for a different purpose after refactoring. En el kernel de Linux versiones anteriores a la versión 5.3.11, el archivo sound/core/timer.c tiene un uso de la memoria previamente liberada causado por una refactorización... • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.11 • CWE-416: Use After Free •
