    (CVE-2021-20321)

  - A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux     kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an     off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this     vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source     port randomization are indirectly affected as well. (CVE-2021-20322)

  - Improper input validation in the Intel(R) Ethernet ixgbe driver for Linux before version 3.17.3 may allow     an authenticated user to potentially enable denial of service via local access. (CVE-2021-33098)

  - A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in     drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption).
    This vulnerability is similar with the older CVE-2019-18808. (CVE-2021-3744)

  - A use-after-free flaw was found in the Linux kernel's Bluetooth subsystem in the way user calls connect to     the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the     system or escalate their privileges. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-3752)

  - arch/mips/net/bpf_jit.c in the Linux kernel before 5.4.10 can generate undesirable machine code when     transforming unprivileged cBPF programs, allowing execution of arbitrary code within the kernel context.
    This occurs because conditional branches can exceed the 128 KB limit of the MIPS architecture.
    (CVE-2021-38300)

  - In __configfs_open_file of file.c, there is a possible use-after-free due to improper locking.

  - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some     regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the     memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)

  - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)

  - prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows     unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds     write. (CVE-2021-41864)

  - A heap-based buffer overflow flaw was found in the Linux kernel FireDTV media card driver, where the user     calls the CA_SEND_MSG ioctl. This flaw allows a local user of the host machine to crash the system or     escalate privileges on the system. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-42739)

  - An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in     the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. (CVE-2021-43389)

  - In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in     drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a     crafted device) to trigger an out-of-bounds write via a crafted length value. (CVE-2021-43975)

  - A vulnerability was found in Linux Kernel, where a     refcount leak in llcp_sock_connect() causing     use-after-free which might lead to privilege     escalations.(CVE-2020-25671)

  - A memory leak vulnerability was found in Linux kernel     in llcp_sock_connect(CVE-2020-25672)

  - An out-of-bounds (OOB) memory write flaw was found in     list_devices in drivers/md/dm-ioctl.c in the     Multi-device driver module in the Linux kernel before     5.12. A bound check failure allows an attacker with     special user (CAP_SYS_ADMIN) privilege to gain access     to out-of-bounds memory leading to a system crash or a     leak of internal kernel information. The highest threat     from this vulnerability is to system     availability.(CVE-2021-31916)

  - An issue was discovered in fs/fuse/fuse_i.h in the     Linux kernel before 5.11.8. A 'stall on CPU' can occur     because a retry loop continually finds the same bad     inode, aka CID-775c5033a0d1.(CVE-2021-28950)

  - Use After Free vulnerability in nfc sockets in the     Linux Kernel before 5.12.4 allows local attackers to     elevate their privileges. In typical configurations,     the issue can only be triggered by a privileged local     user with the CAP_NET_RAW capability.(CVE-2021-23134)

  - An issue was discovered in the Linux kernel through     5.11.x. kernel/bpf/verifier.c performs undesirable     out-of-bounds speculation on pointer arithmetic,     leading to side-channel attacks that defeat Spectre     mitigations and obtain sensitive information from     kernel memory. Specifically, for sequences of pointer     arithmetic operations, the pointer modification     performed by the first operation is not correctly     accounted for when restricting subsequent     operations.(CVE-2021-29155)

  - The bpf verifier in the Linux kernel did not properly     handle mod32 destination register truncation when the     source register was known to be 0. A local attacker     with the ability to load bpf programs could use this     gain out-of-bounds reads in kernel memory leading to     information disclosure (kernel memory), and possibly     out-of-bounds writes that could potentially lead to     code execution. This issue was addressed in the     upstream kernel in commit 9b00f1b78809 ('bpf: Fix     truncation handling for mod32 dst reg wrt zero') and in     Linux stable kernels 5.11.2, 5.10.19, and     5.4.101.(CVE-2021-3444)

  - The Linux kernel before 5.11.14 has a use-after-free in     cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the     CIPSO and CALIPSO refcounting for the DOI definitions     is mishandled, aka CID-ad5d07f4a9cd. This leads to     writing an arbitrary value.(CVE-2021-33033)

  - kernel/bpf/verifier.c in the Linux kernel through     5.12.1 performs undesirable speculative loads, leading     to disclosure of stack content via side-channel     attacks, aka CID-801c6058d14a. The specific concern is     not protecting the BPF stack area against speculative     loads. Also, the BPF stack can contain uninitialized     data that might represent sensitive information     previously operated on by the kernel.(CVE-2021-31829)

  - net/bluetooth/hci_request.c in the Linux kernel through     5.12.2 has a race condition for removal of the HCI     controller.(CVE-2021-32399)

  - In the Linux kernel before 5.12.4,     net/bluetooth/hci_event.c has a use-after-free when     destroying an hci_chan, aka CID-5c4c8c954409. This     leads to writing an arbitrary value.(CVE-2021-33034)

It is exploitable     for privilege escalation on some Linux distributions     where local users have /dev/video0 access, but only if     the driver happens to be loaded. There are multiple     race conditions during streaming stopping in this     driver (part of the V4L2 subsystem). These issues are     caused by wrong mutex locking in     vivid_stop_generating_vid_cap(),     vivid_stop_generating_vid_out(),     sdr_cap_stop_streaming(), and the corresponding     kthreads. At least one of these race conditions leads     to a use-after-free.(CVE-2019-18683)
