A NULL pointer dereference vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow authenticated administrators to launch a denial-of-service (DoS) attack via a network. We have already fixed the vulnerability in the following versions: QTS 5.1.2.2533 build 20230926 and later QuTS hero h5.1.2.2534 build 20230927 and later QuTScloud c5.1.5.2651 and later
CVE-2023-41234 2 Intel, Microsoft 2 Power Gadget, Windows 2026-06-17 N/A 5.0 MEDIUM
NULL pointer dereference in Intel(R) Power Gadget software for Windows all versions may allow an authenticated user to potentially enable denial of service via local access.
CVE-2023-40546 2 Fedoraproject, Redhat 3 Fedora, Enterprise Linux, Shim 2026-06-17 N/A 6.2 MEDIUM
A flaw was found in Shim when an error happened while creating a new ESL variable. If Shim fails to create the new variable, it tries to print an error message to the user; however, the number of parameters used by the logging function doesn't match the format string used by it, leading to a crash under certain circumstances.
CVE-2023-40459 1 Sierrawireless 8 Aleos, Es450, Gx450 and 5 more 2026-06-17 N/A 7.5 HIGH
The ACEManager component of ALEOS 4.16 and earlier does not adequately perform input sanitization during authentication, which could potentially result in a Denial of Service (DoS) condition for ACEManager without impairing other router functions. ACEManager recovers from the DoS condition by restarting within ten seconds of becoming unavailable.
CVE-2023-40360 1 Qemu 1 Qemu 2026-06-17 N/A 5.5 MEDIUM
QEMU through 8.0.4 accesses a NULL pointer in nvme_directive_receive in hw/nvme/ctrl.c because there is no check for whether an endurance group is configured before checking whether Flexible Data Placement is enabled.
CVE-2023-40032 2 Fedoraproject, Libvips 2 Fedora, Libvips 2026-06-17 N/A 5.5 MEDIUM
libvips is a demand-driven, horizontally threaded image processing library. A specially crafted SVG input can cause libvips versions 8.14.3 or earlier to segfault when attempting to parse a malformed UTF-8 character. Users should upgrade to libvips version 8.14.4 (or later) when processing untrusted input.
CVE-2023-3866 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate session id and tree id in the compound request This patch validate session id and tree id in compound request. If first operation in the compound is SMB2 ECHO request, ksmbd bypass session and tree validation. So work->sess and work->tcon could be NULL. If secound request in the compound access work->sess or tcon, It cause NULL pointer dereferecing error.
CVE-2023-3772 4 Debian, Fedoraproject, Linux and 1 more 6 Debian Linux, Fedora, Linux Kernel and 3 more 2026-06-17 N/A 5.5 MEDIUM
A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in xfrm_update_ae_params(), leading to a possible kernel crash and denial of service.
CVE-2023-3603 1 Libssh 1 Libssh 2026-06-17 N/A 3.1 LOW
A missing allocation check in sftp server processing read requests may cause a NULL dereference on low-memory conditions. The malicious client can request up to 4GB SFTP reads, causing allocation of up to 4GB buffers, which was not being checked for failure. This will likely crash the authenticated user's sftp server connection (if implemented as forking as recommended). For thread-based servers, this might also cause DoS for legitimate users. Given this code is not in any released versions, no security releases have been issued.
CVE-2023-3359 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
An issue was discovered in the Linux kernel brcm_nvram_parse in drivers/nvmem/brcm_nvram.c. Lacks for the check of the return value of kzalloc() can cause the NULL Pointer Dereference.
CVE-2023-3358 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
A null pointer dereference was found in the Linux kernel's Integrated Sensor Hub (ISH) driver. This issue could allow a local user to crash the system.
CVE-2023-3357 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel AMD Sensor Fusion Hub driver. This flaw allows a local user to crash the system.
CVE-2023-3355 1 Linux 1 Linux Kernel 2026-06-17 N/A 4.7 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel's drivers/gpu/drm/msm/msm_gem_submit.c code in the submit_lookup_cmds function, which fails because it lacks a check of the return value of kmalloc(). This issue allows a local user to crash the system.
CVE-2023-3354 3 Fedoraproject, Qemu, Redhat 4 Fedora, Qemu, Enterprise Linux and 1 more 2026-06-17 N/A 7.5 HIGH
A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service.
CVE-2023-3338 3 Debian, Linux, Netapp 3 Debian Linux, Linux Kernel, Active Iq Unified Manager 2026-06-17 N/A 6.5 MEDIUM
A null pointer dereference flaw was found in the Linux kernel's DECnet networking protocol. This issue could allow a remote user to crash the system.
CVE-2023-3316 1 Libtiff 1 Libtiff 2026-06-17 N/A 5.9 MEDIUM
A NULL pointer dereference in TIFFClose() is caused by a failure to open an output file (non-existent path or a path that requires permissions like /dev/null) while specifying zones.
CVE-2023-3220 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
An issue was discovered in the Linux kernel through 6.1-rc8. dpu_crtc_atomic_check in drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c lacks check of the return value of kzalloc() and will cause the NULL Pointer Dereference.
CVE-2023-3212 5 Debian, Fedoraproject, Linux and 2 more 14 Debian Linux, Fedora, Linux Kernel and 11 more 2026-06-17 N/A 4.4 MEDIUM
A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic.
CVE-2023-3106 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2026-06-17 N/A 6.6 MEDIUM
A NULL pointer dereference vulnerability was found in netlink_dump. This issue can occur when the Netlink socket receives the message(sendmsg) for the XFRM_MSG_GETSA, XFRM_MSG_GETPOLICY type message, and the DUMP flag is set and can cause a denial of service or possibly another unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely.
CVE-2023-3012 1 Gpac 1 Gpac 2026-06-17 N/A 7.8 HIGH
NULL Pointer Dereference in GitHub repository gpac/gpac prior to 2.2.2.
