CVE-2025-59148 1 Oisf 1 Suricata 2026-06-17 N/A 7.5 HIGH
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Versions 8.0.0 and below incorrectly handle the entropy keyword when not anchored to a "sticky" buffer, which can lead to a segmentation fault. This issue is fixed in version 8.0.1. To workaround this issue, users can disable rules using the entropy keyword, or validate they are anchored to a sticky buffer.
CVE-2025-58472 1 Qnap 1 Qsync Central 2026-06-17 N/A 4.9 MEDIUM
A NULL pointer dereference vulnerability has been reported to affect Qsync Central. If a remote attacker gains an administrator account, they can then exploit the vulnerability to launch a denial-of-service (DoS) attack. We have already fixed the vulnerability in the following version: Qsync Central 5.0.0.4 ( 2026/01/20 ) and later
CVE-2025-58364 1 Openprinting 1 Cups 2026-06-17 N/A 6.5 MEDIUM
OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.12 and earlier, an unsafe deserialization and validation of printer attributes causes null dereference in the libcups library. This is a remote DoS vulnerability available in local subnet in default configurations. It can cause the cups & cups-browsed to crash, on all the machines in local network who are listening for printers (so by default for all regular linux machines). On systems where the vulnerability CVE-2024-47176 (cups-filters 1.x/cups-browsed 2.x vulnerability) was not fixed, and the firewall on the machine does not reject incoming communication to IPP port, and the machine is set to be available to public internet, attack vector "Network" is possible. The current versions of CUPS and cups-browsed projects have the attack vector "Adjacent" in their default configurations. Version 2.4.13 contains a patch for CVE-2025-58364.
CVE-2025-58144 1 Xen 1 Xen 2026-06-17 N/A 7.5 HIGH
[This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] There are two issues related to the mapping of pages belonging to other domains: For one, an assertion is wrong there, where the case actually needs handling. A NULL pointer de-reference could result on a release build. This is CVE-2025-58144. And then the P2M lock isn't held until a page reference was actually obtained (or the attempt to do so has failed). Otherwise the page can not only change type, but even ownership in between, thus allowing domain boundaries to be violated. This is CVE-2025-58145.
CVE-2025-58120 1 F5 3 Big-ip Next Cloud-native Network Functions, Big-ip Next For Kubernetes, Big-ip Next Service Proxy For Kubernetes 2026-06-17 N/A 7.5 HIGH
When HTTP/2 Ingress is configured, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
CVE-2025-57623 1 Totolink 2 N600r, N600r Firmware 2026-06-17 N/A 5.3 MEDIUM
A NULL pointer dereference in TOTOLINK N600R firmware v4.3.0cu.7866_B2022506 allows attackers to cause a Denial of Service.
CVE-2025-57615 1 Meh.schizofreni 1 Rust-ffmpeg 2026-06-17 N/A 7.5 HIGH
An issue was discovered in rust-ffmpeg 0.3.0 (after comit 5ac0527) An integer overflow vulnerability in the Vector::new constructor function allows an attacker to cause a denial of service via a null pointer dereference. The vulnerability stems from an unchecked cast of a usize parameter to c_int, which can result in a negative value being passed to the underlying C function sws_allocVec().
CVE-2025-57613 1 Meh.schizofreni 1 Rust-ffmpeg 2026-06-17 N/A 7.5 HIGH
An issue was discovered in rust-ffmpeg 0.3.0 (after comit 5ac0527) A null pointer dereference vulnerability in the input() constructor function allows an attacker to cause a denial of service. The vulnerability is triggered when the avio_alloc_context() call fails and returns NULL, which is then stored and later dereferenced by the Io struct's Drop implementation.
CVE-2025-57612 1 Meh.schizofreni 1 Rust-ffmpeg 2026-06-17 N/A 7.5 HIGH
An issue was discovered in rust-ffmpeg 0.3.0 (after comit 5ac0527) Null pointer dereference vulnerability in the name() method allows an attacker to cause a denial of service. The vulnerability exists because the method fails to check for a NULL return value from the av_get_sample_fmt_name() C function, which can be triggered by providing an unrecognized sample format.
CVE-2025-57611 1 Meh.schizofreni 1 Rust-ffmpeg 2026-06-17 N/A 5.3 MEDIUM
An issue was discovered in rust-ffmpeg 0.3.0 (after comit 5ac0527) Null pointer dereference vulnerability in the dump() method allows an attacker to cause a denial of service. The vulnerability exists because the method fails to check the return value of avfilter_graph_dump() for NULL, leading to a crash if the underlying memory allocation fails.
CVE-2025-57248 1 Sumatrapdfreader 1 Sumatrapdf 2026-06-17 N/A 7.3 HIGH
A null pointer dereference vulnerability was discovered in SumatraPDF 3.5.2 during the processing of a crafted .djvu file. When the file is opened, the application crashes inside libmupdf.dll, specifically in the DataPool::has_data() function.
CVE-2025-57156 1 Owntone 1 Owntone Server 2026-06-17 N/A 7.5 HIGH
NULL pointer dereference in the dacp_reply_playqueueedit_clear function in src/httpd_dacp.c in owntone-server through commit 6d604a1 (newer commit after version 28.12) allows remote attackers to cause a Denial of Service (crash).
CVE-2025-57155 1 Owntone 1 Owntone Server 2026-06-17 N/A 7.5 HIGH
NULL pointer dereference in the daap_reply_groups function in src/httpd_daap.c in owntone-server through commit 5e6f19a (newer commit after version 28.2) allows remote attackers to cause a Denial of Service.
CVE-2025-56225 1 Fluidsynth 1 Fluidsynth 2026-06-17 N/A 7.5 HIGH
fluidsynth-2.4.6 and earlier versions is vulnerable to Null pointer dereference in fluid_synth_monopoly.c, that can be triggered when loading an invalid midi file.
CVE-2025-55904 1 Open5gs 1 Open5gs 2026-06-17 N/A 4.0 MEDIUM
Open5GS v2.7.5, prior to commit 67ba7f92bbd7a378954895d96d9d7b05d5b64615, is vulnerable to a NULL pointer dereference when a multipart/related HTTP POST request with an empty HTTP body is sent to the SBI of either AMF, AUSF, BSF, NRF, NSSF, PCF, SMF, UDM, or UDR, resulting in a denial of service. This occurs in the parse_multipart function in lib/sbi/message.c.
CVE-2025-55780 1 Artifex 1 Mupdf 2026-06-17 N/A 7.5 HIGH
A null pointer dereference occurs in the function break_word_for_overflow_wrap() in MuPDF 1.26.4 when rendering a malformed EPUB document. Specifically, the function calls fz_html_split_flow() to split a FLOW_WORD node, but does not check if node->next is valid before accessing node->next->overflow_wrap, resulting in a crash if the split fails or returns a partial node chain.
CVE-2025-55698 1 Microsoft 3 Windows 11 24h2, Windows 11 25h2, Windows Server 2025 2026-06-17 N/A 7.7 HIGH
Null pointer dereference in Windows DirectX allows an authorized attacker to deny service over a network.
CVE-2025-55649 1 Gpac 1 Gpac 2026-06-17 N/A 5.5 MEDIUM
A NULL pointer dereference in the gf_media_map_esd function (media_tools/isom_tools.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file.
