| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-08-08 | CVE-2021-38203 | Improper Locking vulnerability in multiple products btrfs in the Linux kernel before 5.13.4 allows attackers to cause a denial of service (deadlock) via processes that trigger allocation of new system chunks during times when there is a shortage of free space in the system space_info. | 2.1 |
| 2021-08-08 | CVE-2021-38204 | Use After Free vulnerability in multiple products drivers/usb/host/max3421-hcd.c in the Linux kernel before 5.13.6 allows physically proximate attackers to cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain situations. | 4.6 |
| 2021-08-08 | CVE-2021-38205 | Access of Uninitialized Pointer vulnerability in multiple products drivers/net/ethernet/xilinx/xilinx_emaclite.c in the Linux kernel before 5.13.3 makes it easier for attackers to defeat an ASLR protection mechanism because it prints a kernel pointer (i.e., the real IOMEM pointer). | 2.1 |
| 2021-08-08 | CVE-2021-38206 | NULL Pointer Dereference vulnerability in Linux Kernel The mac80211 subsystem in the Linux kernel before 5.12.13, when a device supporting only 5 GHz is used, allows attackers to cause a denial of service (NULL pointer dereference in the radiotap parser) by injecting a frame with 802.11a rates. | 2.1 |
| 2021-08-08 | CVE-2021-38207 | Classic Buffer Overflow vulnerability in Linux Kernel drivers/net/ethernet/xilinx/ll_temac_main.c in the Linux kernel before 5.12.13 allows remote attackers to cause a denial of service (buffer overflow and lockup) by sending heavy network traffic for about ten minutes. | 5.0 |
| 2021-08-08 | CVE-2021-38208 | NULL Pointer Dereference vulnerability in Linux Kernel net/nfc/llcp_sock.c in the Linux kernel before 5.12.10 allows local unprivileged users to cause a denial of service (NULL pointer dereference and BUG) by making a getsockname call after a certain type of failure of a bind call. | 2.1 |
| 2021-08-08 | CVE-2021-38209 | Information Exposure Through Discrepancy vulnerability in Linux Kernel net/netfilter/nf_conntrack_standalone.c in the Linux kernel before 5.12.2 allows observation of changes in any net namespace because these changes are leaked into all other net namespaces. | 2.1 |
| 2021-08-07 | CVE-2021-38166 | Integer Overflow or Wraparound vulnerability in multiple products In kernel/bpf/hashtab.c in the Linux kernel through 5.13.8, there is an integer overflow and out-of-bounds write when many elements are placed in a single bucket. | 7.8 |
| 2021-08-05 | CVE-2021-3655 | Improper Input Validation vulnerability in multiple products A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. | 3.3 |
| 2021-08-05 | CVE-2021-3679 | Infinite Loop vulnerability in multiple products A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was found in the way user uses trace ring buffer in a specific way. | 5.5 |
