DATE CVE VULNERABILITY TITLE RISK
2019-12-24 CVE-2019-19947 Use of Uninitialized Resource vulnerability in multiple products
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.
4.6
2019-12-23 CVE-2019-5108 Improper Authentication vulnerability in multiple products
An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3.
3.3
2019-12-22 CVE-2019-19922 Resource Exhaustion vulnerability in multiple products
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.

5.5
2019-12-17 CVE-2019-19241 Unspecified vulnerability in Linux Kernel
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.

2019-12-17 CVE-2019-19816 Out-of-bounds Write vulnerability in multiple products
In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image and performing some operations can cause slab-out-of-bounds write access in __btrfs_map_block in fs/btrfs/volumes.c, because a value of 1 for the number of data stripes is mishandled.

2019-12-12 CVE-2019-19770 Use After Free vulnerability in Linux Kernel
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).

2019-12-12 CVE-2019-19769 Use After Free vulnerability in multiple products
In the Linux kernel 5.3.10, there is a use-after-free (read) in the perf_trace_lock_acquire function (related to include/trace/events/lock.h).

6.7
2019-12-12 CVE-2019-19767 Use After Free vulnerability in Linux Kernel
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.

4.3
2019-12-08 CVE-2019-19448 Use After Free vulnerability in multiple products
In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to a right data structure.

2019-12-08 CVE-2019-19447 Use After Free vulnerability in multiple products
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.
