RE: af_packet: use after free in prb_retire_rx_blk_timer_expired

Hi I find it caused by below steps: 1. set tp_version to TPACKET_V3 and req->tp_block_nr to 1 2. set tp_block_nr to 0 Then pg_vec was freed, and we did not delete the timer? Best Regards, liujian > -Original Message- > From: liujian (CE) > Sent: Sunday, July 23,

RE: af_packet: use after free in prb_retire_rx_blk_timer_expired
