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-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-2024-11499 2026-04-15 4.9 Medium
A vulnerability exists in RTU500 IEC 60870-4-104 controlled station functionality, that allows an authenticated and authorized attacker to perform a CMU restart. The vulnerability can be triggered if certificates are updated while in use on active connections. The affected CMU will automatically recover itself if an attacker successfully exploits this vulnerability.
CVE-2024-20266 1 Cisco 1 Ios Xr Software 2026-04-15 5.3 Medium
A vulnerability in the DHCP version 4 (DHCPv4) server feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to trigger a crash of the dhcpd process, resulting in a denial of service (DoS) condition. This vulnerability exists because certain DHCPv4 messages are improperly validated when they are processed by an affected device. An attacker could exploit this vulnerability by sending a malformed DHCPv4 message to an affected device. A successful exploit could allow the attacker to cause a crash of the dhcpd process. While the dhcpd process is restarting, which may take approximately two minutes, DHCPv4 server services are unavailable on the affected device. This could temporarily prevent network access to clients that join the network during that time period and rely on the DHCPv4 server of the affected device. Notes: Only the dhcpd process crashes and eventually restarts automatically. The router does not reload. This vulnerability only applies to DHCPv4. DHCP version 6 (DHCPv6) is not affected.
