A flaw was found in GNU nano's multi-buffer error message handling. When a user opens multiple files at startup and one triggers an ALERT-level error, a specially crafted filename containing printf format specifiers can be reinterpreted. This format string vulnerability may allow an attacker to achieve stack information disclosure, cause a denial of service (crash), or potentially perform arbitrary memory writes.

CVE-2024-583668.5 HIG22.1%
——7SurrealDB before 1.1.1 contains a format string vulnerability in the rquickjs Exception::throw_type function when scripting is enabled. Attackers with scripting privileges can supply format string sequences in error inputs to read arbitrary memory or execute code with SurrealDB process privileges.2dCVE-2026-158097.8 HIG2.7%
——1A flaw was found in CRI-O. The fix for a previous vulnerability (CVE-2022-4318) was incorrect, allowing it to be bypassed. An attacker capable of setting environment variables on a container can inject a newline character into the HOME environment variable. This issue allows the addition of arbitrary lines into /etc/passwd by use of a specially crafted environment variable.7dCVE-2026-156807.5 HIG17.6%
——5Lorex 2K Indoor Wi-Fi Security Camera CDeviceOperator Format String Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Lorex 2K Indoor Wi-Fi Security Cameras. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the parsing of JSON requests in the sonia binary. The issue results from the lack of proper validation of a user-supplied string before using it as a format specifier. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-25884.9dCVE-2026-464655.5 MED14.9%
——4Dell PowerProtect Data Domain, versions 7.7.1.0 through 8.7, LTS2026 release version 8.6.1.0 through 8.6.1.10, LTS2025 release version 8.3.1.0 through 8.3.1.30, LTS2024 release versions 7.13.1.0 through 7.13.1.70 contain an use of externally-controlled format string vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Information disclosure and denial of service.15dCVE-2026-502119.8 CRI21.1%
——6Leftover engineering diagnostics and factory-level diagnostic software remain exposed on retail builds, giving malicious apps write privileges to internal NVRAM registers.13hCVE-2026-332109.1 CRI54.0%
——16Ruby JSON is a JSON implementation for Ruby. From version 2.14.0 to before versions 2.15.2.1, 2.17.1.2, and 2.19.2, a format string injection vulnerability can lead to denial of service attacks or information disclosure, when the allow_duplicate_key: false parsing option is used to parse user supplied documents. This issue has been patched in versions 2.15.2.1, 2.17.1.2, and 2.19.2.2d
