The function directly assigns NULL to gchan->config, losing the\n   reference to the original memory\n4. The original memory becomes unreachable and cannot be freed\n\nFix this by using a temporary variable to hold the krealloc() result\nand only updating gchan->config when the allocation succeeds.\n\nFound via static analysis and code review.\n\n## Affected\n\n- `linux_kernel >= 5.11.1, < 5.15.199`\n- `linux_kernel >= 5.16, < 6.1.162`\n- `linux_kernel >= 6.2, < 6.6.122`\n- `linux_kernel >= 6.7, < 6.12.67`\n- `linux_kernel >= 6.13, < 6.18.7`\n- `linux_kernel = 5.11`\n- `linux_kernel = 6.19`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.18.7`","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":221613,"id":"CVE-2026-23026","ts":1792035289379,"field":"cvss","old":null,"new":"5.5"},{"seq":221612,"id":"CVE-2026-23026","ts":1792035289379,"field":"severity","old":"none","new":"medium"}]}
