CVE-2021-43976 5 Debian, Fedoraproject, Linux and 2 more 23 Debian Linux, Fedora, Linux Kernel and 20 more 2026-06-17 2.1 LOW 4.6 MEDIUM
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).
CVE-2021-43975 4 Debian, Fedoraproject, Linux and 1 more 18 Debian Linux, Fedora, Linux Kernel and 15 more 2026-06-17 4.6 MEDIUM 6.7 MEDIUM
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-2021-43389 4 Debian, Linux, Oracle and 1 more 6 Debian Linux, Linux Kernel, Communications Cloud Native Core Binding Support Function and 3 more 2026-06-17 2.1 LOW 5.5 MEDIUM
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-2021-43267 3 Fedoraproject, Linux, Netapp 16 Fedora, Linux Kernel, H300e and 13 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of user-supplied sizes for the MSG_CRYPTO message type.
CVE-2021-43057 2 Linux, Netapp 17 Linux Kernel, H300e, H300e Firmware and 14 more 2026-06-17 7.2 HIGH 7.8 HIGH
An issue was discovered in the Linux kernel before 5.14.8. A use-after-free in selinux_ptrace_traceme (aka the SELinux handler for PTRACE_TRACEME) could be used by local attackers to cause memory corruption and escalate privileges, aka CID-a3727a8bac0a. This occurs because of an attempt to access the subjective credentials of another task.
CVE-2021-43056 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2026-06-17 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S implementation bug in the handling of the SRR1 register values.
CVE-2021-42739 5 Debian, Fedoraproject, Linux and 2 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2026-06-17 4.6 MEDIUM 6.7 MEDIUM
The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandles bounds checking.
CVE-2021-42327 3 Fedoraproject, Linux, Netapp 18 Fedora, Linux Kernel, H300e and 15 more 2026-06-17 4.6 MEDIUM 6.7 MEDIUM
dp_link_settings_write in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within parse_write_buffer_into_params when it uses the size of copy_from_user to copy a userspace buffer into a 40-byte heap buffer.
CVE-2021-42083 3 Linux, Microsoft, Osnexus 3 Linux Kernel, Windows, Quantastor 2026-06-17 N/A 8.7 HIGH
An authenticated attacker is able to create alerts that trigger a stored XSS attack. POC * go to the alert manager * open the ITSM tab * add a webhook with the URL/service token value ' -h && id | tee /tmp/ttttttddddssss #' (whitespaces are tab characters) * click add * click apply * create a test alert * The test alert will run the command “id | tee /tmp/ttttttddddssss” as root. * after the test alert inspect /tmp/ttttttddddssss it'll contain the ids of the root user.
CVE-2021-42056 3 Linux, Microsoft, Thalesgroup 3 Linux Kernel, Windows, Safenet Authentication Client 2026-06-17 7.2 HIGH 6.7 MEDIUM
Thales Safenet Authentication Client (SAC) for Linux and Windows through 10.7.7 creates insecure temporary hid and lock files allowing a local attacker, through a symlink attack, to overwrite arbitrary files, and potentially achieve arbitrary command execution with high privileges.
CVE-2021-42008 3 Debian, Linux, Netapp 20 Debian Linux, Linux Kernel, H300e and 17 more 2026-06-17 6.9 MEDIUM 7.8 HIGH
The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access.
CVE-2021-41073 4 Debian, Fedoraproject, Linux and 1 more 21 Debian Linux, Fedora, Linux Kernel and 18 more 2026-06-17 7.2 HIGH 7.8 HIGH
loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc/<pid>/maps for exploitation.
CVE-2021-40830 3 Amazon, Linux, Opengroup 4 Amazon Web Services Aws-c-io, Amazon Web Services Internet Of Things Device Software Development Kit V2, Linux Kernel and 1 more 2026-06-17 5.8 MEDIUM 6.3 MEDIUM
The AWS IoT Device SDK v2 for Java, Python, C++ and Node.js appends a user supplied Certificate Authority (CA) to the root CAs instead of overriding it on Unix systems. TLS handshakes will thus succeed if the peer can be verified either from the user-supplied CA or the system’s default trust-store. Attackers with access to a host’s trust stores or are able to compromise a certificate authority already in the host's trust store (note: the attacker must also be able to spoof DNS in this case) may be able to use this issue to bypass CA pinning. An attacker could then spoof the MQTT broker, and either drop traffic and/or respond with the attacker's data, but they would not be able to forward this data on to the MQTT broker because the attacker would still need the user's private keys to authenticate against the MQTT broker. The 'aws_tls_ctx_options_override_default_trust_store_*' function within the aws-c-io submodule has been updated to override the default trust store. This corrects this issue. This issue affects: Amazon Web Services AWS IoT Device SDK v2 for Java versions prior to 1.5.0 on Linux/Unix. Amazon Web Services AWS IoT Device SDK v2 for Python versions prior to 1.6.1 on Linux/Unix. Amazon Web Services AWS IoT Device SDK v2 for C++ versions prior to 1.12.7 on Linux/Unix. Amazon Web Services AWS IoT Device SDK v2 for Node.js versions prior to 1.5.3 on Linux/Unix. Amazon Web Services AWS-C-IO 0.10.4 on Linux/Unix.
CVE-2021-40745 3 Adobe, Linux, Microsoft 3 Campaign, Linux Kernel, Windows 2026-06-17 5.0 MEDIUM 7.5 HIGH
Adobe Campaign version 21.2.1 (and earlier) is affected by a Path Traversal vulnerability that could lead to reading arbitrary server files. By leveraging an exposed XML file, an unauthenticated attacker can enumerate other files on the server.
CVE-2021-3923 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2026-06-17 N/A 2.3 LOW
A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it can be further used to defeat existing kernel protection mechanisms.
CVE-2021-3864 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2026-06-17 N/A 7.0 HIGH
A flaw was found in the way the dumpable flag setting was handled when certain SUID binaries executed its descendants. The prerequisite is a SUID binary that sets real UID equal to effective UID, and real GID equal to effective GID. The descendant will then have a dumpable value set to 1. As a result, if the descendant process crashes and core_pattern is set to a relative value, its core dump is stored in the current directory with uid:gid permissions. An unprivileged local user with eligible root SUID binary could use this flaw to place core dumps into root-owned directories, potentially resulting in escalation of privileges.
