This, in turn, calls  \ngred_offload, where memset could receive a NULL pointer as input,  \npotentially leading to a kernel crash.  \n  \nWhen table->opt is NULL in gred_init(), gred_change_table_def()  \nis not called yet, so it is not necessary to call ->ndo_setup_tc()  \nin gred_offload(). \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"01 Apr 2025\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2025-04-01T19:44:24.000000Z"}
