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-2019-19241 – 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://packetstorm.news/files/id/155669 •
CVE-2019-19767 – kernel: use-after-free in __ext4_expand_extra_isize and ext4_xattr_set_entry related to fs/ext4/inode.c and fs/ext4/super.c
https://notcve.org/view.php?id=CVE-2019-19767
12 Dec 2019 — The Linux kernel before 5.4.2 mishandles ext4_expand_extra_isize, as demonstrated by use-after-free errors in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c, aka CID-4ea99936a163. El kernel de Linux versión anterior a 5.4.2 maneja inapropiadamente la función ext4_expand_extra_isize, como es demostrado por un error de uso de la memoria previamente liberada en las funciones __ext4_expand_extra_isize y ext4_xattr_set_entry, relacionadas con los archivos fs/ex... • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html • CWE-416: Use After Free •

12 Dec 2019 — In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously created with a call to another debugfs function such as debugfs_create_file).

05 Dec 2019 — fpregs_state_valid in arch/x86/include/asm/fpu/internal.h in the Linux kernel before 5.4.2, when GCC 9 is used, allows context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact because of incorrect fpu_fpregs_owner_ctx caching, as demonstrated by mishandling of signal-based non-cooperative preemption in Go 1.14 prereleases on amd64, aka CID-59c4bd853abc.
