The issue stemmed from calling am65_cpsw_nuss_phylink_cleanup() too early, which invalidated the phylink structure before it was used in the network device cleanup routine. The fix moves the cleanup call to after am65_cpsw_nuss_cleanup_ndev() to maintain correct resource ordering. Without this fix, unloading the driver under certain runtime conditions (e.g., active link) would lead to a kernel oops and possible system instability due to invalid memory access.", "threat_severity": "Moderate"}
