This could lead to a kernel crash\nwhen the invalid pointers are later dereferenced by clock core\nfunctions.\n\nFix this by:\n1. Changing clk_get() to the device-managed devm_clk_get().\n2. Adding IS_ERR() checks immediately after each clock acquisition.\n\n## Affected\n\n- `linux_kernel >= 5.16, < 6.19.9`\n- `linux_kernel = 7.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.19.9`","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":222284,"id":"CVE-2026-43443","ts":1792065866515,"field":"cvss","old":null,"new":"5.5"},{"seq":222283,"id":"CVE-2026-43443","ts":1792065866515,"field":"severity","old":"none","new":"medium"}]}
