When calling platform_get_irq fails, the function returns immediately, bypassing cleanup and leaving allocated resources in memory. Although this flaw cannot be directly leveraged for code execution or privilege escalation, repeated failures can deplete kernel memory over time, potentially degrading system performance, triggering out\u2011of\u2011memory conditions, or causing system instability. The weakness is a classic example of a memory leak, which can be especially problematic on embedded Tegra platforms with limited memory budgets.", "risk_and_exploitability": "The CVE carries a very low exploitation probability, as evidenced by an EPSS score of less than 1%, and it is not listed in the CISA KEV catalog. The attack vector is inferred to be local, requiring the attacker to trigger errors in the platform_get_irq path, which is generally limited to privileged system operations or manufacturing conditions. Because the issue is a resource exhaustion flaw rather than an immediate security breach, the overall threat remains low to moderate but warrants remediation to preserve system reliability."}}}}, "created": "2026-02-16T09:43:54.332081+00:00", "updated": "2026-04-18T12:15:15.791640+00:00", "vendors": ["linux", "linux$PRODUCT$linux_kernel"], "weaknesses": ["CWE-401"]}
