    CVE-2020-36158     mwifiex_cmd_802_11_ad_hoc_start in drivers/net/wireless/marvell/mwifiex/join.c in the Linux kernel through     5.10.4 might allow remote attackers to execute arbitrary code via a long SSID value, aka CID-5c455c5ab332.
    CVE-2020-36386     An issue was discovered in the Linux kernel before 5.8.1. net/bluetooth/hci_event.c has a slab out-of-     bounds read in hci_extended_inquiry_result_evt, aka CID-51c19bf3d5cf.
    CVE-2021-0129     Improper access control in BlueZ may allow an authenticated user to potentially enable information     disclosure via adjacent access.
    CVE-2021-20194     There is a vulnerability in the linux kernel versions higher than 5.2 (if kernel compiled with config     params CONFIG_BPF_SYSCALL=y , CONFIG_BPF=y , CONFIG_CGROUPS=y , CONFIG_CGROUP_BPF=y ,     CONFIG_HARDENED_USERCOPY not set, and BPF hook to getsockopt is registered). As result of BPF execution,     the local user can trigger bug in __cgroup_bpf_run_filter_getsockopt() function that can lead to heap     overflow (because of non-hardened usercopy). The impact of attack could be deny of service or possibly     privileges escalation.
    CVE-2021-20239     A flaw was found in the Linux kernel in versions before 5.4.92 in the BPF protocol. This flaw allows an     attacker with a local account to leak information about kernel internal addresses. The highest threat from     this vulnerability is to confidentiality.
    CVE-2021-23133     A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel     privilege escalation from the context of a network service or an unprivileged process. If     sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the     auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network     service privileges to escalate to root or from the context of an unprivileged user directly if a     BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket.
    CVE-2021-28950     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-2021-28971     In intel_pmu_drain_pebs_nhm in arch/x86/events/intel/ds.c in the Linux kernel through 5.11.8 on some     Haswell CPUs, userspace applications (such as perf-fuzzer) can cause a system crash because the PEBS     status in a PEBS record is mishandled, aka CID-d88d05a9e0b6.
    CVE-2021-29155     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-2021-29646     An issue was discovered in the Linux kernel before 5.11.11. tipc_nl_retrieve_key in net/tipc/node.c does     not properly validate certain data sizes, aka CID-0217ed2848e8.
    CVE-2021-29650     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.
    CVE-2021-31440     This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel     5.11.15. An attacker must first obtain the ability to execute low-privileged code on the target system in     order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The     issue results from the lack of proper validation of user-supplied eBPF programs prior to executing them.
    An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the     context of the kernel. Was ZDI-CAN-13661.
    CVE-2021-31829     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-2021-31916     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-2021-33200     kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic     operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel     memory, leading to local privilege escalation to root. In particular, there is a corner case where the off     reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.
    CVE-2021-3348     nbd_add_socket in drivers/block/nbd.c in the Linux kernel through 5.10.12 has an ndb_queue_rq use-after-     free that could be triggered by local attackers (with access to the nbd device) via an I/O request at a     certain point during device setup, aka CID-b98e762e3d71.
    CVE-2021-33909     fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer     allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an     unprivileged user, aka CID-8cae8cd89f05.
    CVE-2021-3489     The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size     was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel     and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee (bpf, ringbuf: Deny     reserve of buffers larger than ringbuf) (v5.13-rc4) and backported to the stable kernels in v5.12.4,     v5.11.21, and v5.10.37. It was introduced via 457f44363a88 (bpf: Implement BPF ring buffer and verifier     support for it) (v5.8-rc1).

An update of the bluez package has been released.

The version of kernel installed on the remote host is prior to 4.14.238-182.421. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1685 advisory.

    A vulnerability was found in the bluez, where Passkey Entry protocol used in Secure Simple Pairing (SSP),     Secure Connections (SC) and LE Secure Connections (LESC) of the Bluetooth Core Specification is vulnerable     to an impersonation attack where an active attacker can impersonate the initiating device without any     previous knowledge. (CVE-2020-26558)

    A flaw was found in the Linux kernel. Improper access control in BlueZ may allow an authenticated user to     potentially enable information disclosure via adjacent access. The highest threat from this vulnerability     is to data confidentiality and integrity. (CVE-2021-0129)

    A denial-of-service (DoS) flaw was identified  in the Linux kernel due to an incorrect memory barrier in     xt_replace_table in net/netfilter/x_tables.c in the netfilter subsystem. (CVE-2021-29650)

    A flaw was found in the Linux kernel's handling of the removal of Bluetooth HCI controllers. This flaw     allows an attacker with a local account to exploit a race condition, leading to corrupted memory and     possible privilege escalation. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-32399)

    A use-after-free flaw was found in hci_send_acl in the bluetooth host controller interface (HCI) in Linux     kernel, where a local attacker with an access rights could cause a denial of service problem on the system     The issue results from the object hchan, freed in hci_disconn_loglink_complete_evt, yet still used in     other places. The highest threat from this vulnerability is to data integrity, confidentiality and system     availability. (CVE-2021-33034)

    In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because     of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a     side-channel attack, aka CID-9183671af6db. (CVE-2021-33624)

    A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in     the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the     system. (CVE-2021-3564)

    A flaw use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in     the way user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call     hci_unregister_dev() together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(),     hci_get_conn_info(), hci_get_auth_info(). A privileged local user could use this flaw to crash the system     or escalate their privileges on the system. (CVE-2021-3573)

    In the Linux kernel, the following vulnerability has been resolved:

    HID: usbhid: fix info leak in hid_submit_ctrl

    In hid_submit_ctrl(), the way of calculating the report length doesn'ttake into account that report->size     can be zero. When running thesyzkaller reproducer, a report of size 0 causes hid_submit_ctrl) tocalculate     transfer_buffer_length as 16384. When this urb is passed tothe usb core layer, KMSAN reports an info leak     of 16384 bytes.

    To fix this, first modify hid_report_len() to account for the zeroreport size case by using DIV_ROUND_UP     for the division. Then, call itfrom hid_submit_ctrl(). (CVE-2021-46906)
