CVE-2026-1152494.6 MED—
———A flaw has been found in subhajitkhan online-clinic-management-system up to e9ee77a8827a1446220fa07ee693dc4d9a29a578. Impacted is an unknown function of the file patappointtime.php of the component Appointment Booking. This manipulation of the argument day/time/appdate causes improper input validation. The attack can be initiated remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.17hCVE-2026-922088.8 ALT—
———NoMachine mDNS Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NoMachine. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the parsing of mDNS resource records. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-30982.2dCVE-2026-1111839.8 CRÍ—
———GStreamer rtpL16depay Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.
The specific flaw exists within the processing of RTP payload elements. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-31143.2dCVE-2026-765057.5 ALT—
———A vulnerability in the IPv4 packet processing functionality of Cisco IOS XR Software that affects Cisco ASR 9000 and 9900 Series Aggregation Services Routers as well as Cisco ASR 9902 and 9903 Compact High-Performance Routers could allow an unauthenticated, remote attacker to cause network processor (NP) errors, resulting in a line card reset or shutdown and a denial of service (DoS) condition.
This vulnerability is due to the incorrect handling of crafted IPv4 packets that are received on an affected line card interface and processed as for-us traffic. The issue can result in an NP reset, causing traffic loss on the affected line card while it recovers. Under repeated reset conditions, the network processor may enter a persistent shutdown state, in which case an explicit line card reload may be required to restore traffic.
The vulnerability is within the IPv4 packet-processing path. Transit IPv4 traffic does not trigger this issue and IPv6 traffic cannot trigger it.18hCVE-2026-764768.8 ALT—
———As part of Cisco's ongoing commitment to proactive security and product quality, engineering teams for Cisco Emergency Responder, Cisco Prime Collaboration Deployment, Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), and Cisco Unity Connection have conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-76476 are related to issues concerning improper input validation that are grouped under the Common Weakness Enumeration (CWE) Class CWE-20.18hCVE-2026-764625.5 MED—
———A vulnerability in the interprocess communication (IPC) channel of the Secure Firewall Posture module in Cisco Secure Client could allow an authenticated, local attacker to elevate privileges on an affected device.
This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a series of crafted IPC messages to a local socket. A successful exploit could allow the attacker to perform limited file write operations on the filesystem with SYSTEM or root privileges.
Although this vulnerability affects the Secure Firewall Posture module in Cisco Secure Client on Windows, macOS, and Linux operating systems, this vulnerability could be used to obtain full root privileges on macOS and Linux. For that reason Cisco has assigned this security advisory a Security Impact Rating (SIR) of High rather than Medium as the score indicates.2d
