Descripción técnica

In the Linux kernel, the following vulnerability has been resolved: net: mana: Use pci_name() for debugfs directory naming Use pci_name(pdev) for the per-device debugfs directory instead of hardcoded "0" for PFs and pci_slot_name(pdev->slot) for VFs. The previous approach had two issues: 1. pci_slot_name() dereferences pdev->slot, which can be NULL for VFs in environments like generic VFIO passthrough or nested KVM, causing a NULL pointer dereference. 2. Multiple PFs would all use "0", and VFs across different PCI domains or buses could share the same slot name, leading to -EEXIST errors from debugfs_create_dir(). pci_name(pdev) returns the unique BDF address, is always valid, and is unique across the system.

CVE-2026-828035.3 MED

—

———A vulnerability has been found in armink struct2json 1.0. This affects the function S2J_STRUCT_GET_string_ELEMENT in the library struct2json/inc/s2jdef.h of the component JSON Deserialization. The manipulation of the argument valuestring leads to null pointer dereference. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.13h CVE-2026-825884.3 MED

——7A vulnerability was identified in Open5GS up to 2.7.7. This issue affects some unknown processing of the file src/amf/namf-handler.c of the component Transfer Endpoint. Such manipulation leads to null pointer dereference. The attack can be launched remotely. Upgrading to version 2.8.0 is capable of addressing this issue. The name of the patch is abf8a836564b966b5141110fc25ed413c4f17522. Upgrading the affected component is advised.1d CVE-2026-772174.9 MED

——11PLANET GS-4210-16P2S firmware before 3.441b260626 contains authenticated stack buffer overflow and null pointer dereference vulnerabilities in /cgi-bin/dispatcher.cgi. The web_radiusSrv*_post family of handlers copies the radKey, radKey_0, radDftParamKey, radName, and radIp POST parameters into fixed-size stack buffers without length validation, and additionally dereferences radName and radIp without verifying their presence in the request. A remote authenticated attacker can send crafted requests to crash the CGI process or web management service, resulting in denial of service.10h CVE-2026-751254.9 MED

——10PLANET GS-4210-16P2S firmware before 3.441b260626 contains an authenticated null pointer dereference vulnerability in /cgi-bin/dispatcher.cgi. The web_poe_alive_rmtip_post handler dereferences the rmtIP parameter without verifying its presence. A remote authenticated attacker can send a crafted request omitting the rmtIP parameter to cause the CGI process to dereference a null pointer and crash, resulting in denial of service of the web management interface.3d CVE-2026-540845.3 MED

——1Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. In versions 4.0.0 through 4.14.6, a malicious or man-in-the-middle enrollment manager can crash a Wazuh agent during enrollment by returning a malformed key response with fewer than four fields, causing a NULL pointer dereference. The w_enrollment_process_agent_key() routine splits the manager-provided key into four space-separated fields but does not verify that all fields are present before passing them to validators. Because OS_StrBreak() leaves missing trailing entries as NULL and OS_IsValidName() calls strlen() on its argument without a NULL check, a response such as OSSEC K:'1' reaches OS_IsValidName(NULL) and terminates the agent process. Since Wazuh permits enrollment against an unverified manager when no CA certificate is configured, an attacker operating a rogue manager or intercepting the enrollment flow can deterministically crash agents, resulting in denial of service. This issue is fixed in version 4.14.7.3d CVE-2026-383447.5 ALT
