Vulnerability details
The vulnerability allows a local user to corrupt network interface statistics and generate excessive log entries.
The vulnerability exists due to improper check for unusual or exceptional conditions in icssg_ndo_get_stats64() in the TI ICSSG ethernet driver when retrieving PA statistics on hardware without a PA stats block. A local user can trigger regular statistics polling to corrupt network interface statistics and generate excessive log entries.
The issue occurs because a negative error value is accumulated into unsigned statistics fields, resulting in incorrect rx_errors, rx_dropped, and tx_dropped counters.
