DATE CVE VULNERABILITY TITLE RISK
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.

2019-12-17 CVE-2019-19814 Out-of-bounds Write vulnerability in Linux Kernel 5.0.21
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.

2019-12-15 CVE-2019-19807 Use After Free vulnerability in multiple products
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.

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-2019-19768 Use After Free vulnerability in Linux Kernel 5.4.0
In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-buffer).

2019-12-11 CVE-2019-14899 Man-in-the-Middle vulnerability in multiple products
A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream.

2019-12-08 CVE-2019-19449 Out-of-bounds Read vulnerability in Linux Kernel 5.0.21
In the Linux kernel 5.0.21, mounting a crafted f2fs filesystem image can lead to slab-out-of-bounds read access in f2fs_build_segment_manager in fs/f2fs/segment.c, related to init_min_max_mtime in fs/f2fs/segment.c (because the second argument to get_seg_entry is not validated).

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.
