CVE-2022-0907 4 Debian, Fedoraproject, Libtiff and 1 more 4 Debian Linux, Fedora, Libtiff and 1 more 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
Unchecked Return Value to NULL Pointer Dereference in tiffcrop in libtiff 4.3.0 allows attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit f2b656e2.
CVE-2022-0485 1 Redhat 2 Enterprise Linux, Libnbd 2026-06-17 N/A 4.8 MEDIUM
A flaw was found in the copying tool `nbdcopy` of libnbd. When performing multi-threaded copies using asynchronous nbd calls, nbdcopy was blindly treating the completion of an asynchronous command as successful, rather than checking the *error parameter. This could result in the silent creation of a corrupted destination image.
CVE-2021-4189 4 Debian, Netapp, Python and 1 more 5 Debian Linux, Ontap Select Deploy Administration Utility, Python and 2 more 2026-06-17 N/A 5.3 MEDIUM
A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which otherwise would not have been possible.
CVE-2021-47360 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: binder: make sure fd closes complete During BC_FREE_BUFFER processing, the BINDER_TYPE_FDA object cleanup may close 1 or more fds. The close operations are completed using the task work mechanism -- which means the thread needs to return to userspace or the file object may never be dereferenced -- which can lead to hung processes. Force the binder thread back to userspace if an fd is closed during BC_FREE_BUFFER handling.
CVE-2021-42780 3 Fedoraproject, Opensc Project, Redhat 3 Fedora, Opensc, Enterprise Linux 2026-06-17 5.0 MEDIUM 5.3 MEDIUM
A use after return issue was found in Opensc before version 0.22.0 in insert_pin function that could potentially crash programs using the library.
CVE-2021-41041 2 Eclipse, Oracle 2 Openj9, Java Se 2026-06-17 5.0 MEDIUM 5.3 MEDIUM
In Eclipse Openj9 before version 0.32.0, Java 8 & 11 fail to throw the exception captured during bytecode verification when verification is triggered by a MethodHandle invocation, allowing unverified methods to be invoked using MethodHandles.
CVE-2021-40401 3 Debian, Fedoraproject, Gerbv Project 3 Debian Linux, Fedora, Gerbv 2026-06-17 6.8 MEDIUM 8.6 HIGH
A use-after-free vulnerability exists in the RS-274X aperture definition tokenization functionality of Gerbv 2.7.0 and dev (commit b5f1eacd) and Gerbv forked 2.7.1. A specially-crafted gerber file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2021-3998 2 Gnu, Netapp 12 Glibc, H300s, H300s Firmware and 9 more 2026-06-17 N/A 7.5 HIGH
A flaw was found in glibc. The realpath() function can mistakenly return an unexpected value, potentially leading to information leakage and disclosure of sensitive data.
CVE-2021-3911 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2026-06-17 4.3 MEDIUM 4.2 MEDIUM
If the ROA that a repository returns contains too many bits for the IP address then OctoRPKI will crash.
CVE-2021-3673 2 Fedoraproject, Radare 2 Fedora, Radare2 2026-06-17 5.0 MEDIUM 7.5 HIGH
A vulnerability was found in Radare2 in version 5.3.1. Improper input validation when reading a crafted LE binary can lead to resource exhaustion and DoS.
CVE-2021-3659 3 Fedoraproject, Linux, Redhat 17 Fedora, Linux Kernel, Codeready Linux Builder and 14 more 2026-06-17 N/A 5.5 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability.
CVE-2021-39643 1 Google 1 Android 2026-06-17 4.6 MEDIUM 6.7 MEDIUM
In ic_startRetrieveEntryValue of acropora/app/identity/ic.c, there is a possible bypass of defense-in-depth due to missing validation of the return value. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-195573629References: N/A
CVE-2021-38171 2 Debian, Ffmpeg 2 Debian Linux, Ffmpeg 2026-06-17 7.5 HIGH 9.8 CRITICAL
adts_decode_extradata in libavformat/adtsenc.c in FFmpeg 4.4 does not check the init_get_bits return value, which is a necessary step because the second argument to init_get_bits can be crafted.
CVE-2021-38114 2 Debian, Ffmpeg 2 Debian Linux, Ffmpeg 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
libavcodec/dnxhddec.c in FFmpeg 4.4 does not check the return value of the init_vlc function, a similar issue to CVE-2013-0868.
CVE-2021-37625 1 Skytable 1 Skytable 2026-06-17 5.0 MEDIUM 7.5 HIGH
Skytable is an open source NoSQL database. In versions prior to 0.6.4 an incorrect check of return value of the accept function in the run-loop for a TCP socket/TLS socket/TCP+TLS multi-socket causes an early exit from the run loop that should continue infinitely unless terminated by a local user, effectively causing the whole database server to shut down. This has severe impact and can be used to easily cause DoS attacks without the need to use much bandwidth. The attack vectors include using an incomplete TLS connection for example by not providing the certificate for the connection and using a specially crafted TCP packet that triggers the application layer backoff algorithm.
CVE-2021-34585 2 Codesys, Wago 55 Codesys, 750-8202, 750-8202 Firmware and 52 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
In the CODESYS V2 web server prior to V1.1.9.22 crafted web server requests can trigger a parser error. Since the parser result is not checked under all conditions, a pointer dereference with an invalid address can occur. This leads to a denial of service situation.
CVE-2021-34405 2 Google, Nvidia 2 Android, Shield Experience 2026-06-17 4.9 MEDIUM 5.5 MEDIUM
NVIDIA Linux distributions contain a vulnerability in TrustZone’s TEE_Malloc function, where an unchecked return value causing a null pointer dereference may lead to denial of service.
CVE-2021-32845 1 Mobyproject 1 Hyperkit 2026-06-17 N/A 7.7 HIGH
HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107 and prior of HyperKit, the implementation of `qnotify` at `pci_vtrnd_notify` fails to check the return value of `vq_getchain`. This leads to `struct iovec iov;` being uninitialized and used to read memory in `len = (int) read(sc->vrsc_fd, iov.iov_base, iov.iov_len);` when an attacker is able to make `vq_getchain` fail. This issue may lead to a guest crashing the host causing a denial of service and, under certain circumstance, memory corruption. This issue is fixed in commit 41272a980197917df8e58ff90642d14dec8fe948.
CVE-2021-31366 1 Juniper 17 Junos, Mx10, Mx10003 and 14 more 2026-06-17 3.3 LOW 6.5 MEDIUM
An Unchecked Return Value vulnerability in the authd (authentication daemon) of Juniper Networks Junos OS on MX Series configured for subscriber management / BBE allows an adjacent attacker to cause a crash by sending a specific username. This impacts authentication, authorization, and accounting (AAA) services on the MX devices and leads to a Denial of Service (DoS) condition. Continued receipted of these PPP login request will create a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS 15.1 versions prior to 15.1R7-S9; 17.3 versions prior to 17.3R3-S12; 17.4 versions prior to 17.4R3-S5; 18.1 versions prior to 18.1R3-S13; 18.2 versions prior to 18.2R3-S8; 18.3 versions prior to 18.3R3-S5; 18.4 versions prior to 18.4R3-S9; 19.1 versions prior to 19.1R3-S6; 19.2 versions prior to 19.2R1-S7, 19.2R3-S3; 19.3 versions prior to 19.3R2-S6, 19.3R3-S3; 19.4 versions prior to 19.4R3-S3; 20.1 versions prior to 20.1R3; 20.2 versions prior to 20.2R3-S1; 20.3 versions prior to 20.3R3; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2.
CVE-2021-29853 1 Ibm 1 Planning Analytics 2026-06-17 4.0 MEDIUM 4.3 MEDIUM
IBM Planning Analytics 2.0 could expose information that could be used to to create attacks by not validating the return values from some methods or functions. IBM X-Force ID: 205529.
