CVE ID :CVE-2026-40494
Published : April 18, 2026, 3:16 a.m. | 21 hours, 25 minutes ago
Description :SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. Prior to commit 45d48d1f2e8e0d73e80bc1fd5310cb57f4547302, the TGA codec’s RLE decoder in `tga.c` has an asymmetric bounds check vulnerability. The run-packet path (line 297) correctly clamps the repeat count to the remaining buffer space, but the raw-packet path (line 305-311) has no equivalent bounds check. This allows writing up to 496 bytes of attacker-controlled data past the end of a heap buffer. Commit 45d48d1f2e8e0d73e80bc1fd5310cb57f4547302 patches the issue.
Severity: 9.8 | CRITICAL

⚠️ Vulnerability Description:
1. IMMEDIATE ACTIONS
Isolate any identified or suspected MeshCore control plane instances from the production network. Immediately block all external unauthenticated access attempts to MeshCore API endpoints at the network perimeter using firewalls or API Gateways. Review MeshCore control plane logs thoroughly for indicators of compromise, such as unusual configuration changes, unexpected process spawns, or outbound connections to unknown destinations. Initiate your organization's incident response procedures immediately upon detection or strong suspicion of exploitation. Collect forensic data from potentially affected systems, including memory dumps, disk images, and network captures, before applying any remediation actions that might alter crucial evidence.
