Technical description

IBM Power Systems Firmware FW1060.00 through FW1060.81 is affected by a vulnerability in the service processor mailbox interface. An attacker with authenticated service-level access to the FSP can send a specially crafted mailbox message to overflow host firmware runtime attribute storage, allowing arbitrary code to be executed in the host firmware runtime. This gives the attacker full access to the managed system's memory and hardware interfaces, resulting in a confidentiality, integrity, and availability impact to the managed system.

——4In EmberZNet 9.1.1 and earlier, a malformed Publish Price Matrix command can result in an out-of-bounds write potentially leading to remote code execution. These messages must come from a device that has already joined the network. Only devices supporting the Price Cluster are impacted.1d CVE-2026-85080—

——8In EmberZNet 9.1.1 and earlier, a malformed GetGroupMembership message can result in an out-of-bounds write leading to a crash. A limited number of values can be written using this vulnerability, so no route to remote code execution was observed. These messages must come from a device that has already joined the network. Only devices supporting the Group Cluster are impacted.1d CVE-2026-85079—

——7In EmberZNet 9.1.1 and earlier, a malformed Simple_Desc_req response can result in an out-of-bounds write potentially leading to remote code execution. This response must come from a device that has already joined the network, and the attacker must wait for a Simple_Desc_req before the attack can be performed.1d CVE-2026-11438310.0 CRI

——15A weakness has been identified in TOTOLINK EX200 5.2.3c.7200. This impacts the function setWiFiAclAddConfig of the file /cgi-bin/cstecgi.cgi of the component wireless.so. This manipulation of the argument macAddress causes stack-based buffer overflow. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks.1d CVE-2026-11438210.0 CRI

——15A security flaw has been discovered in TOTOLINK EX200 5.2.3c.7200. This affects the function setStaticDhcpConfig of the file /cgi-bin/cstecgi.cgi of the component lan.so. The manipulation of the argument Comment results in stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks.1d CVE-2026-921837.8 HIG

——9GIMP APNG File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of APNG files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29400.2d
