CVE-2025-14958 is a heap-based buffer overflow vulnerability identified in the floooh sokol graphics library, specifically within the _sg_pipeline_common_init function in sokol_gfx.h. This function is responsible for initializing graphics pipeline state, and improper handling of input data leads to a heap overflow condition. The vulnerability requires local access with low privileges (AV:L, PR:L) and no user interaction, indicating that an attacker must have some form of local code execution or access to the system to trigger the flaw. The overflow can corrupt heap memory, potentially allowing an attacker to execute arbitrary code, crash the application, or cause denial of service. The product follows a rolling release model, which means updates are continuously delivered without discrete version numbers, complicating vulnerability management. The patch is identified by the commit hash 33e2271c431bf21de001e972f72da17a984da932, which addresses the buffer overflow. The CVSS 4.0 base score is 4.8 (medium severity), reflecting the limited attack vector and privileges required but acknowledging the potential impact on system stability and security. No known exploits are currently reported in the wild, but public exploit code availability increases the risk of exploitation. Organizations using the sokol library, especially in local or embedded graphics applications, should apply the patch promptly to prevent exploitation.

For European organizations, the primary impact of this vulnerability lies in potential local privilege escalation, arbitrary code execution, or denial of service within applications embedding the floooh sokol graphics library. Since the attack requires local access, the threat is more significant in environments where multiple users share systems or where attackers can gain initial footholds via other means. Industries relying on embedded systems, graphical applications, or custom software using sokol may face risks of system instability or compromise. Confidentiality could be impacted if attackers leverage the overflow to execute code and access sensitive data. Integrity and availability are also at risk due to possible application crashes or malicious code execution. The medium severity rating suggests a moderate but non-trivial risk, especially in critical infrastructure or industrial control systems using this library. The rolling release model may delay patch deployment if organizations do not have robust update mechanisms. Overall, the threat could disrupt operations, lead to data breaches, or facilitate further attacks if exploited.

European organizations should take the following specific steps: 1) Identify all software and systems using the floooh sokol library, particularly those embedding sokol_gfx.h. 2) Verify the version or commit hash of the library in use to determine if it is vulnerable (prior to or at commit 33e2271c431bf21de001e972f72da17a984da932). 3) Apply the patch corresponding to commit 33e2271c431bf21de001e972f72da17a984da932 immediately to remediate the buffer overflow. 4) Implement strict local access controls and monitoring to limit the ability of untrusted users to execute code locally. 5) Employ runtime protections such as heap canaries, address space layout randomization (ASLR), and control flow integrity (CFI) in applications using sokol to reduce exploitation likelihood. 6) Conduct code audits and fuzz testing on custom integrations of the library to detect similar vulnerabilities. 7) Maintain an up-to-date inventory of dependencies and integrate continuous vulnerability scanning in the development lifecycle to catch rolling release updates. 8) Educate developers and system administrators about the risks of local buffer overflows and the importance of patching rolling release software promptly.
