In the Linux kernel, the following vulnerability has been resolved: i40e: Fix kernel crash during module removal The driver incorrectly frees client instance and subsequent i40e module removal leads to kernel crash. Reproducer: 1. Do ethtool offline test followed immediately by another one host# ethtool -t eth0 offline; ethtool -t eth0 offline 2. Remove recursively irdma module that also removes i40e module host# modprobe -r irdma Result: [ 8675.035651] i40e 0000:3d:00.0 eno1: offline testing starting [ 8675.193774] i40e 0000:3d:00.0 eno1: testing finished [ 8675.201316] i40e 0000:3d:00.0 eno1: offline testing starting [ 8675.358921] i40e 0000:3d:00.0 eno1: testing finished [ 8675.496921] i40e 0000:3d:00.0: IRDMA hardware initialization FAILED init_state=2 status=-110 [ 8686.188955] i40e 0000:3d:00.1: i40e_ptp_stop: removed PHC on eno2 [ 8686.943890] i40e 0000:3d:00.1: Deleted LAN device PF1 bus=0x3d dev=0x00 func=0x01 [ 8686.952669] i40e 0000:3d:00.0: i40e_ptp_stop: removed PHC on eno1 [ 8687.761787] BUG: kernel NULL pointer dereference, address: 0000000000000030 [ 8687.768755] #PF: supervisor read access in kernel mode [ 8687.773895] #PF: error_code(0x0000) - not-present page [ 8687.779034] PGD 0 P4D 0 [ 8687.781575] Oops: 0000 [#1] PREEMPT SMP NOPTI [ 8687.785935] CPU: 51 PID: 172891 Comm: rmmod Kdump: loaded Tainted: G W I 5.19.0+ #2 [ 8687.794800] Hardware name: Intel Corporation S2600WFD/S2600WFD, BIOS SE5C620.86B.0X.02.0001.051420190324 05/14/2019 [ 8687.805222] RIP: 0010:i40e_lan_del_device+0x13/0xb0 [i40e] [ 8687.810719] Code: d4 84 c0 0f 84 b8 25 01 00 e9 9c 25 01 00 41 bc f4 ff ff ff eb 91 90 0f 1f 44 00 00 41 54 55 53 48 8b 87 58 08 00 00 48 89 fb 8b 68 30 48 89 ef e8 21 8a 0f d5 48 89 ef e8 a9 78 0f d5 48 8b [ 8687.829462] RSP: 0018:ffffa604072efce0 EFLAGS: 00010202 [ 8687.834689] RAX: 0000000000000000 RBX: ffff8f43833b2000 RCX: 0000000000000000 [ 8687.841821] RDX: 0000000000000000 RSI: ffff8f4b0545b298 RDI: ffff8f43833b2000 [ 8687.848955] RBP: ffff
