| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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. | 5.5 |
| 2019-12-11 | CVE-2019-14899 | 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. | 7.4 |
| 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). | 7.8 |
| 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. | 7.8 |
| 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. | 7.8 |
| 2019-12-05 | CVE-2019-19602 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products 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. | 6.1 |
| 2019-12-03 | CVE-2019-19543 | Use After Free vulnerability in Linux Kernel In the Linux kernel before 5.1.6, there is a use-after-free in serial_ir_init_module() in drivers/media/rc/serial_ir.c. | 7.8 |
| 2019-12-03 | CVE-2019-19537 | Race Condition vulnerability in Linux Kernel 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. | 4.2 |
| 2019-12-03 | CVE-2019-19536 | Missing Initialization of Resource vulnerability in multiple products In the Linux kernel before 5.2.9, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_pro.c driver, aka CID-ead16e53c2f0. | 4.6 |
| 2019-12-03 | CVE-2019-19535 | Missing Initialization of Resource vulnerability in multiple products In the Linux kernel before 5.2.9, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_fd.c driver, aka CID-30a8beeb3042. | 4.6 |
