CVE-2026-22993 1 Linux 1 Linux Kernel 2026-04-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: idpf: Fix RSS LUT NULL ptr issue after soft reset During soft reset, the RSS LUT is freed and not restored unless the interface is up. If an ethtool command that accesses the rss lut is attempted immediately after reset, it will result in NULL ptr dereference. Also, there is no need to reset the rss lut if the soft reset does not involve queue count change. After soft reset, set the RSS LUT to default values based on the updated queue count only if the reset was a result of a queue count change and the LUT was not configured by the user. In all other cases, don't touch the LUT. Steps to reproduce: ** Bring the interface down (if up) ifconfig eth1 down ** update the queue count (eg., 27->20) ethtool -L eth1 combined 20 ** display the RSS LUT ethtool -x eth1 [82375.558338] BUG: kernel NULL pointer dereference, address: 0000000000000000 [82375.558373] #PF: supervisor read access in kernel mode [82375.558391] #PF: error_code(0x0000) - not-present page [82375.558408] PGD 0 P4D 0 [82375.558421] Oops: Oops: 0000 [#1] SMP NOPTI <snip> [82375.558516] RIP: 0010:idpf_get_rxfh+0x108/0x150 [idpf] [82375.558786] Call Trace: [82375.558793] <TASK> [82375.558804] rss_prepare.isra.0+0x187/0x2a0 [82375.558827] rss_prepare_data+0x3a/0x50 [82375.558845] ethnl_default_doit+0x13d/0x3e0 [82375.558863] genl_family_rcv_msg_doit+0x11f/0x180 [82375.558886] genl_rcv_msg+0x1ad/0x2b0 [82375.558902] ? __pfx_ethnl_default_doit+0x10/0x10 [82375.558920] ? __pfx_genl_rcv_msg+0x10/0x10 [82375.558937] netlink_rcv_skb+0x58/0x100 [82375.558957] genl_rcv+0x2c/0x50 [82375.558971] netlink_unicast+0x289/0x3e0 [82375.558988] netlink_sendmsg+0x215/0x440 [82375.559005] __sys_sendto+0x234/0x240 [82375.559555] __x64_sys_sendto+0x28/0x30 [82375.560068] x64_sys_call+0x1909/0x1da0 [82375.560576] do_syscall_64+0x7a/0xfa0 [82375.561076] ? clear_bhb_loop+0x60/0xb0 [82375.561567] entry_SYSCALL_64_after_hwframe+0x76/0x7e <snip>
CVE-2026-21243 1 Microsoft 8 Windows Server 2019, Windows Server 2019 (server Core Installation), Windows Server 2022 and 5 more 2026-04-15 7.5 High
Null pointer dereference in Windows LDAP - Lightweight Directory Access Protocol allows an unauthorized attacker to deny service over a network.
CVE-2026-3776 4 Apple, Foxit, Foxitsoftware and 1 more 6 Macos, Pdf Editor, Pdf Reader and 3 more 2026-04-15 5.5 Medium
The application does not validate the presence of required appearance (AP) data before accessing stamp annotation resources. When a PDF contains a stamp annotation missing its AP entry, the code continues to dereference the associated object without a prior null or validity check, which allows a crafted document to trigger a null pointer dereference and crash the application, resulting in denial of service.
CVE-2026-40227 2 Systemd, Systemd Project 2 Systemd, Systemd 2026-04-15 6.2 Medium
In systemd 260 before 261, a local unprivileged user can trigger an assert via an IPC API call with an array or map that has a null element.
CVE-2024-34044 2026-04-15 5.3 Medium
The O-RAN E2T I-Release buildPrometheusList function can have a NULL pointer dereference because peerInfo can be NULL.
CVE-2024-55511 2026-04-15 7.8 High
A null pointer dereference vulnerability in Macrium Reflect prior to 8.1.8017 allows a local attacker to cause a system crash or potentially elevate their privileges via executing a specially crafted executable.
CVE-2025-14841 1 Offis 1 Dcmtk 2026-04-15 3.3 Low
A flaw has been found in OFFIS DCMTK up to 3.6.9. The impacted element is the function DcmQueryRetrieveIndexDatabaseHandle::startFindRequest/DcmQueryRetrieveIndexDatabaseHandle::startMoveRequest in the library dcmqrdb/libsrc/dcmqrdbi.cc of the component dcmqrscp. This manipulation causes null pointer dereference. The attack requires local access. Upgrading to version 3.7.0 is sufficient to resolve this issue. Patch name: ffb1a4a37d2c876e3feeb31df4930f2aed7fa030. You should upgrade the affected component.
CVE-2024-10037 2026-04-15 4.4 Medium
A vulnerability exists in the RTU500 web server component that can cause a denial of service to the RTU500 CMU application if a specially crafted message sequence is executed on a WebSocket connection. An attacker must be properly authenticated and the test mode function of RTU500 must be enabled to exploit this vulnerability. The affected CMU will automatically recover itself if an attacker successfully exploits this vulnerability.
CVE-2025-13425 1 Google 1 Osv-scalibr 2026-04-15 3.3 Low
A bug in the filesystem traversal fallback path causes fs/diriterate/diriterate.go:Next() to overindex an empty slice when ReadDir returns nil for an empty directory, resulting in a panic (index out of range) and an application crash (denial of service) in OSV-SCALIBR.
CVE-2023-45925 1 Midnight Commander 1 Midnight Commander 2026-04-15 N/A
GNU Midnight Commander 4.8.29-146-g299d9a2fb was discovered to contain a NULL pointer dereference via the function x_error_handler() at tty/x11conn.c. NOTE: this is disputed because it should be categorized as a usability problem (an X operation silently fails).
CVE-2024-24446 1 Openairinterface 1 Cn5g Amf 2026-04-15 6.5 Medium
An uninitialized pointer dereference in OpenAirInterface CN5G AMF up to v2.0.0 allows attackers to cause a Denial of Service (DoS) via a crafted InitialContextSetupResponse message sent to the AMF.
CVE-2025-20071 2026-04-15 6.5 Medium
NULL pointer dereference for some Intel(R) Graphics Drivers may allow an authenticated user to potentially enable denial of service via local access.
CVE-2024-20446 1 Cisco 1 Nx-os 2026-04-15 8.6 High
A vulnerability in the DHCPv6 relay agent of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of specific fields in a DHCPv6 RELAY-REPLY message. An attacker could exploit this vulnerability by sending a crafted DHCPv6 packet to any IPv6 address that is configured on an affected device. A successful exploit could allow the attacker to cause the dhcp_snoop process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition.
CVE-2025-30195 1 Powerdns 1 Recursor 2026-04-15 7.5 High
An attacker can publish a zone containing specific Resource Record Sets. Processing and caching results for these sets can lead to an illegal memory accesses and crash of the Recursor, causing a denial of service. The remedy is: upgrade to the patched 5.2.1 version. We would like to thank Volodymyr Ilyin for bringing this issue to our attention.
CVE-2025-0430 2026-04-15 7.5 High
Belledonne Communications Linphone-Desktop is vulnerable to a NULL Dereference vulnerability, which could allow a remote attacker to create a denial-of-service condition.
CVE-2025-33237 1 Nvidia 5 Driver, Geforce, Nvs and 2 more 2026-04-15 5.5 Medium
NVIDIA HD Audio Driver for Windows contains a vulnerability where an attacker could exploit a NULL pointer dereference issue. A successful exploit of this vulnerability might lead to a denial of service.
CVE-2023-45924 1 Opengl 1 Libglvnd-bb06db5a 2026-04-15 9.8 Critical
libglxproto.c in OpenGL libglvnd bb06db5a was discovered to contain a segmentation violation via the function glXGetDrawableScreen(). NOTE: this is disputed because there are no common situations in which users require uninterrupted operation with an attacker-controller server.
CVE-2025-70954 1 Ton-blockchain 1 Ton 2026-04-15 7.5 High
A Null Pointer Dereference vulnerability exists in the TON Virtual Machine (TVM) within the TON Blockchain before v2025.06. The issue is located in the execution logic of the INMSGPARAM instruction, where the program fails to validate if a specific pointer is null before accessing it. By sending a malicious transaction or smart contract, an attacker can trigger this null pointer dereference, causing the validator node process to crash (segmentation fault). This results in a Denial of Service (DoS) affecting the availability of the entire blockchain network.
CVE-2024-56430 2026-04-15 2.9 Low
OpenFHE through 1.2.3 has a NULL pointer dereference in BinFHEContext::EvalFloor in lib/binfhe-base-scheme.cpp.
