DATE CVE VULNERABILITY TITLE RISK
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.

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.

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.

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.

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
2021-08-02 CVE-2021-34556 Information Exposure Through Discrepancy vulnerability in multiple products
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack.

5.5
2021-08-02 CVE-2021-35477 Information Exposure Through Discrepancy vulnerability in multiple products
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value.

2021-07-21 CVE-2021-37159 Use After Free vulnerability in multiple products
hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.
