CVE-2021-35538 3 Apple, Linux, Oracle 4 Macos, Linux Kernel, Solaris and 1 more 2026-06-17 4.6 MEDIUM 7.8 HIGH
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is Prior to 6.1.28. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful attacks of this vulnerability can result in takeover of Oracle VM VirtualBox. Note: This vulnerability does not apply to Windows systems. CVSS 3.1 Base Score 7.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
CVE-2021-35039 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-06-17 6.9 MEDIUM 7.8 HIGH
kernel/module.c in the Linux kernel before 5.12.14 mishandles Signature Verification, aka CID-0c18f29aae7c. Without CONFIG_MODULE_SIG, verification that a kernel module is signed, for loading via init_module, does not occur for a module.sig_enforce=1 command-line argument.
CVE-2021-34981 1 Linux 1 Linux Kernel 2026-06-17 N/A 6.7 MEDIUM
Linux Kernel Bluetooth CMTP Module Double Free Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the CMTP module. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the kernel. Was ZDI-CAN-11977.
CVE-2021-34788 3 Apple, Cisco, Linux 3 Macos, Anyconnect Secure Mobility Client, Linux Kernel 2026-06-17 6.9 MEDIUM 7.0 HIGH
A vulnerability in the shared library loading mechanism of Cisco AnyConnect Secure Mobility Client for Linux and Mac OS could allow an authenticated, local attacker to perform a shared library hijacking attack on an affected device if the VPN Posture (HostScan) Module is installed on the AnyConnect client. This vulnerability is due to a race condition in the signature verification process for shared library files that are loaded on an affected device. An attacker could exploit this vulnerability by sending a series of crafted interprocess communication (IPC) messages to the AnyConnect process. A successful exploit could allow the attacker to execute arbitrary code on the affected device with root privileges. To exploit this vulnerability, the attacker must have a valid account on the system.
CVE-2021-34691 2 Idrive, Linux 2 Remotepc, Linux Kernel 2026-06-17 5.0 MEDIUM 7.5 HIGH
iDrive RemotePC before 4.0.1 on Linux allows denial of service. A remote and unauthenticated attacker can disconnect a valid user session by connecting to an ephemeral port.
CVE-2021-34425 5 Apple, Google, Linux and 2 more 6 Iphone Os, Macos, Android and 3 more 2026-06-17 4.0 MEDIUM 4.7 MEDIUM
The Zoom Client for Meetings before version 5.7.3 (for Android, iOS, Linux, macOS, and Windows) contain a server side request forgery vulnerability in the chat\'s "link preview" functionality. In versions prior to 5.7.3, if a user were to enable the chat\'s "link preview" feature, a malicious actor could trick the user into potentially sending arbitrary HTTP GET requests to URLs that the actor cannot reach directly.
CVE-2021-34424 5 Apple, Google, Linux and 2 more 30 Iphone Os, Macos, Android and 27 more 2026-06-17 5.0 MEDIUM 7.5 HIGH

CVE-2021-34400 3 Linux, Microsoft, Nvidia 137 Linux Kernel, Windows, Dgx-1 P100 and 134 more 2026-06-17 2.1 LOW 4.1 MEDIUM
NVIDIA GPU and Tegra hardware contain a vulnerability in the internal microcontroller which may allow a user with elevated privileges to gain access to information from unscrubbed memory, which may lead to information disclosure.
CVE-2021-34399 3 Linux, Microsoft, Nvidia 137 Linux Kernel, Windows, Dgx-1 P100 and 134 more 2026-06-17 2.1 LOW 4.1 MEDIUM
NVIDIA GPU and Tegra hardware contain a vulnerability in the internal microcontroller which may allow a user with elevated privileges to gain access to information from unscrubbed registers, which may lead to information disclosure.
CVE-2021-33909 6 Debian, Fedoraproject, Linux and 3 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2026-06-17 7.2 HIGH 7.8 HIGH
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-2021-33391 2 Htacg, Linux 2 Tidy, Linux Kernel 2026-06-17 N/A 9.8 CRITICAL
An issue in HTACG HTML Tidy v5.7.28 allows attacker to execute arbitrary code via the -g option of the CleanNode() function in gdoc.c.
CVE-2021-33254 2 Embedthis, Linux 2 Appweb, Linux Kernel 2026-06-17 5.0 MEDIUM 7.5 HIGH
An issue was discovered in src/http/httpLib.c in EmbedThis Appweb Community Edition 8.2.1, allows attackers to cause a denial of service via the stream paramter to the parseUri function.
CVE-2021-33200 3 Fedoraproject, Linux, Netapp 19 Fedora, Linux Kernel, Cloud Backup and 16 more 2026-06-17 7.2 HIGH 7.8 HIGH
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-2021-32606 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2026-06-17 7.2 HIGH 7.8 HIGH
In the Linux kernel 5.11 through 5.12.2, isotp_setsockopt in net/can/isotp.c allows privilege escalation to root by leveraging a use-after-free. (This does not affect earlier versions that lack CAN ISOTP SF_BROADCAST support.)
CVE-2021-32399 3 Debian, Linux, Netapp 19 Debian Linux, Linux Kernel, Cloud Backup and 16 more 2026-06-17 4.4 MEDIUM 7.0 HIGH
net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller.
CVE-2021-32078 1 Linux 1 Linux Kernel 2026-06-17 6.6 MEDIUM 7.1 HIGH
An Out-of-Bounds Read was discovered in arch/arm/mach-footbridge/personal-pci.c in the Linux kernel through 5.12.11 because of the lack of a check for a value that shouldn't be negative, e.g., access to element -2 of an array, aka CID-298a58e165e4.
CVE-2021-31916 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2026-06-17 6.1 MEDIUM 6.7 MEDIUM
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-2021-31829 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-06-17 2.1 LOW 5.5 MEDIUM
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.
