2.1
None Local Low Not required None None Partial
In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).

2.1
None Local Low Not required None None Partial
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.
3 CVE-2021-38207 120 DoS Overflow 2021-08-08 2021-10-18
5.0
None Remote Low Not required None None Partial
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.
4 CVE-2021-38206 476 DoS 2021-08-08 2021-08-12
2.1
None Local Low Not required None None Partial
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.
5 CVE-2021-38204 416 DoS 2021-08-08 2022-01-04
4.6
None Local Low Not required Partial Partial Partial
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.
6 CVE-2021-38203 770 DoS 2021-08-08 2021-10-07
2.1
None Local Low Not required None None Partial
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.
7 CVE-2021-38202 125 DoS 2021-08-08 2021-10-07
5.0
None Remote Low Not required None None Partial
fs/nfsd/trace.h in the Linux kernel before 5.13.4 might allow remote attackers to cause a denial of service (out-of-bounds read in strlen) by sending NFS traffic when the trace event framework is being used for nfsd.
8 CVE-2021-38201 119 DoS Overflow 2021-08-08 2021-10-07
5.0
None Remote Low Not required None None Partial
net/sunrpc/xdr.c in the Linux kernel before 5.13.4 allows remote attackers to cause a denial of service (xdr_set_page_base slab-out-of-bounds access) by performing many NFS 4.2 READ_PLUS operations.
9 CVE-2021-38200 476 DoS 2021-08-08 2021-08-12
2.1
None Local Low Not required None None Partial
arch/powerpc/perf/core-book3s.c in the Linux kernel before 5.12.13, on systems with perf_event_paranoid=-1 and no specific PMU driver support registered, allows local users to cause a denial of service (perf_instruction_pointer NULL pointer dereference and OOPS) via a "perf record" command.
10 CVE-2021-38199 DoS 2021-08-08 2021-12-21
3.3
None Local Network Low Not required None None Partial
fs/nfs/nfs4client.c in the Linux kernel before 5.13.4 has incorrect connection-setup ordering, which allows operators of remote NFSv4 servers to cause a denial of service (hanging of mounts) by arranging for those servers to be unreachable during trunking detection.
11 CVE-2021-29650 DoS 2021-03-30 2021-06-23
4.9
None Local Low Not required None None Complete
An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows attackers to cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf.
12 CVE-2021-29265 362 DoS 2021-03-26 2021-06-23
4.7
None Local Medium Not required None None Complete
An issue was discovered in the Linux kernel before 5.11.7. usbip_sockfd_store in drivers/usb/usbip/stub_dev.c allows attackers to cause a denial of service (GPF) because the stub-up sequence has race conditions during an update of the local and shared status, aka CID-9380afd6df70.
13 CVE-2021-28964 362 DoS 2021-03-22 2021-06-23
1.9
None Local Medium Not required None None Partial
A race condition was discovered in get_old_root in fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (BUG) because of a lack of locking on an extent buffer before a cloning operation, aka CID-dbcc7d57bffc.
14 CVE-2021-28951 DoS 2021-03-20 2021-04-30
4.9
None Local Low Not required None None Complete
An issue was discovered in fs/io_uring.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (deadlock) because exit may be waiting to park a SQPOLL thread, but concurrently that SQPOLL thread is waiting for a signal to start, aka CID-3ebba796fa25.
15 CVE-2021-28038 770 DoS 2021-03-05 2021-04-09
4.9
None Local Low Not required None None Complete
An issue was discovered in the Linux kernel through 5.11.3, as used with Xen PV. A certain part of the netback driver lacks necessary treatment of errors such as failed memory allocations (as a result of changes to the handling of grant mapping errors). A host OS denial of service may occur during misbehavior of a networking frontend driver. NOTE: this issue exists because of an incomplete fix for CVE-2021-26931.
16 CVE-2021-20317 665 DoS 2021-09-27 2021-12-21
4.9
None Local Low Not required None None Complete
A flaw was found in the Linux kernel. A corrupted timer tree caused the task wakeup to be missing in the timerqueue_add function in lib/timerqueue.c. This flaw allows a local attacker with special user privileges to cause a denial of service, slowing and eventually stopping the system while running OSP.
17 CVE-2021-20219 697 DoS 2021-03-23 2021-03-26
2.1
None Local Low Not required None None Partial
A denial of service vulnerability was found in n_tty_receive_char_special in drivers/tty/n_tty.c of the Linux kernel. In this flaw a local attacker with a normal user privilege could delay the loop (due to a changing ldata->read_head, and a missing sanity check) and cause a threat to the system availability.
18 CVE-2021-3679 400 DoS 2021-08-05 2022-01-01
2.1
None Local Low Not required None None Partial
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. Only privileged local users (with CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.
19 CVE-2020-36311 DoS 2021-04-07 2021-07-21
2.1
None Local Low Not required None None Partial
An issue was discovered in the Linux kernel before 5.9. arch/x86/kvm/svm/sev.c allows attackers to cause a denial of service (soft lockup) by triggering destruction of a large SEV VM (which requires unregistering many encrypted regions), aka CID-7be74942f184.
