A NULL pointer dereference issue was discovered in the Linux kernel in the MPTCP protocol when traversing the subflow list at disconnect time. A local user could use this flaw to potentially crash the system causing a denial of service.
CVE-2023-6622 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2025-06-25 5.5 Medium
A null pointer dereference vulnerability was found in nft_dynset_init() in net/netfilter/nft_dynset.c in nf_tables in the Linux kernel. This issue may allow a local attacker with CAP_NET_ADMIN user privilege to trigger a denial of service.
CVE-2025-0287 1 Paragon-software 6 Paragon Backup \& Recovery, Paragon Disk Wiper, Paragon Drive Copy and 3 more 2025-06-25 5.1 Medium
Various Paragon Software products contain a null pointer dereference vulnerability within biontdrv.sys that is caused by a lack of a valid MasterLrp structure in the input buffer, allowing an attacker to execute arbitrary code in the kernel, facilitating privilege escalation.
CVE-2024-11705 1 Mozilla 2 Firefox, Thunderbird 2025-06-24 9.1 Critical
`NSC_DeriveKey` inadvertently assumed that the `phKey` parameter is always non-NULL. When it was passed as NULL, a segmentation fault (SEGV) occurred, leading to crashes. This behavior conflicted with the PKCS#11 v3.0 specification, which allows `phKey` to be NULL for certain mechanisms. This vulnerability affects Firefox < 133 and Thunderbird < 133.
CVE-2025-45331 2025-06-24 7.5 High
brplot v420.69.1 contains a Null Pointer Dereference (NPD) vulnerability in the br_dagens_handle_once function of its data processing module, leading to unpredictable program behavior, causing segmentation faults, and program crashes.
CVE-2023-52508 1 Linux 1 Linux Kernel 2025-06-24 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: nvme-fc: Prevent null pointer dereference in nvme_fc_io_getuuid() The nvme_fc_fcp_op structure describing an AEN operation is initialized with a null request structure pointer. An FC LLDD may make a call to nvme_fc_io_getuuid passing a pointer to an nvmefc_fcp_req for an AEN operation. Add validation of the request structure pointer before dereference.
CVE-2025-46399 1 Redhat 1 Enterprise Linux 2025-06-24 4.7 Medium
A flaw was found in fig2dev. This vulnerability allows availability via local input manipulation via genge_itp_spline function.
CVE-2025-48705 2025-06-23 7.5 High
An issue was discovered in COROS PACE 3 through 3.0808.0. Due to a NULL pointer dereference vulnerability, sending a crafted BLE message forces the device to reboot.
CVE-2025-6496 2025-06-23 3.3 Low
A vulnerability was found in HTACG tidy-html5 5.8.0. It has been declared as problematic. This vulnerability affects the function InsertNodeAsParent of the file src/parser.c. The manipulation leads to null pointer dereference. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used.
CVE-2025-6375 2025-06-23 3.3 Low
A vulnerability was found in poco up to 1.14.1. It has been rated as problematic. Affected by this issue is the function MultipartInputStream of the file Net/src/MultipartReader.cpp. The manipulation leads to null pointer dereference. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. Upgrading to version 1.14.2 is able to address this issue. The patch is identified as 6f2f85913c191ab9ddfb8fae781f5d66afccf3bf. It is recommended to upgrade the affected component.
CVE-2025-29547 1 Horizondatasys 1 Rollback Rx Pro 2025-06-23 7 High
In Rollback Rx Professional 12.8.0.0, the driver file shieldm.sys allows local users to cause a denial of service because of a null pointer dereference from IOCtl 0x96202000.
CVE-2025-4478 1 Redhat 1 Enterprise Linux 2025-06-23 7.1 High
A flaw was found in the FreeRDP used by Anaconda's remote install feature, where a crafted RDP packet could trigger a segmentation fault. This issue causes the service to crash and remain defunct, resulting in a denial of service. It occurs pre-boot and is likely due to a NULL pointer dereference. Rebooting is required to recover the system.
CVE-2024-31030 2 Keith-cullen, Keithcullen 2 Freecoap, Freecoap 2025-06-20 9.1 Critical
An issue in coap_msg.c in Keith Cullen's FreeCoAP v.0.7 allows remote attackers to cause a Denial of Service or potentially disclose information via a specially crafted packet.
CVE-2023-6603 1 Ffmpeg 1 Ffmpeg 2025-06-20 7.5 High
A flaw was found in FFmpeg's HLS playlist parsing. This vulnerability allows a denial of service via a maliciously crafted HLS playlist that triggers a null pointer dereference during initialization.
CVE-2024-46922 1 Samsung 4 Exynos 1480, Exynos 1480 Firmware, Exynos 2400 and 1 more 2025-06-20 7.5 High
An issue was discovered in Samsung Mobile Processor Exynos 1480 and 2400. The absence of a null check leads to a Denial of Service at amdgpu_cs_parser_bos in the Xclipse Driver.
CVE-2025-33057 2025-06-20 6.5 Medium

CVE-2024-43911 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-06-19 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix NULL dereference at band check in starting tx ba session In MLD connection, link_data/link_conf are dynamically allocated. They don't point to vif->bss_conf. So, there will be no chanreq assigned to vif->bss_conf and then the chan will be NULL. Tweak the code to check ht_supported/vht_supported/has_he/has_eht on sta deflink.
