CVE-2025-60007 1 Juniper 42 Ex2300, Ex2300-c, Ex3400 and 39 more 2026-06-17 N/A 5.5 MEDIUM
A NULL Pointer Dereference vulnerability in the chassis daemon (chassisd) of Juniper Networks Junos OS on MX, SRX and EX Series allows a local attacker with low privileges to cause a Denial-of-Service (DoS). When a user executes the 'show chassis' command with specifically crafted options, chassisd will crash and restart. Due to this all components but the Routing Engine (RE) in the chassis are reinitialized, which leads to a complete service outage, which the system automatically recovers from. This issue affects: Junos OS on MX, SRX and EX Series, except MX10000 Series and MX304:  * all versions before 22.4R3-S8, * 23.2 versions before 23.2R2-S5, * 23.4 versions before 23.4R2-S6, * 24.2 versions before 24.2R2-S2, * 24.4 versions before 24.4R2.
CVE-2025-5867 1 Rt-thread 1 Rt-thread 2026-06-17 7.7 HIGH 8.0 HIGH
A vulnerability classified as critical was found in RT-Thread 5.1.0. This vulnerability affects the function csys_sendto of the file rt-thread/components/lwp/lwp_syscall.c. The manipulation of the argument to leads to null pointer dereference.
CVE-2025-59668 2026-06-17 N/A 7.5 HIGH
Multiple versions of Central Monitor CNS-6201 contain a NULL pointer dereference vulnerability. When processing a crafted certain UDP packet, the affected device may abnormally terminate.
CVE-2025-59386 1 Qnap 1 Quts Hero 2026-06-17 N/A 4.9 MEDIUM
A NULL pointer dereference vulnerability has been reported to affect several QNAP operating system versions. 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: QuTS hero h5.3.2.3354 build 20251225 and later
CVE-2025-59351 1 Linuxfoundation 1 Dragonfly 2026-06-17 N/A 5.3 MEDIUM
Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, the first return value of a function is dereferenced even when the function returns an error. This can result in a nil dereference, and cause code to panic. This vulnerability is fixed in 2.1.0.
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-2025-57623 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.
