Title
ice: prevent NULL pointer deref during reload
Summary
In the Linux kernel, the following vulnerability has been resolved: ice: prevent NULL pointer deref during reload Calling ethtool during reload can lead to call trace, because VSI isn't configured for some time, but netdev is alive. To fix it add rtnl lock for VSI deconfig and config. Set ::num_q_vectors to 0 after freeing and add a check for ::tx/rx_rings in ring related ethtool ops. Add proper unroll of filters in ice_start_eth(). Reproduction: $watch -n 0.1 -d 'ethtool -g enp24s0f0np0' $devlink dev reload pci/0000:18:00.0 action driver_reinit Call trace before fix: [66303.926205] BUG: kernel NULL pointer dereference, address: 0000000000000000 [66303.926259] #PF: supervisor read access in kernel mode [66303.926286] #PF: error_code(0x0000) - not-present page [66303.926311] PGD 0 P4D 0 [66303.926332] Oops: 0000 [#1] PREEMPT SMP PTI [66303.926358] CPU: 4 PID: 933821 Comm: ethtool Kdump: loaded Tainted: G OE 6.4.0-rc5+ #1 [66303.926400] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.00.01.0014.070920180847 07/09/2018 [66303.926446] RIP: 0010:ice_get_ringparam+0x22/0x50 [ice] [66303.926649] Code: 90 90 90 90 90 90 90 90 f3 0f 1e fa 0f 1f 44 00 00 48 8b 87 c0 09 00 00 c7 46 04 e0 1f 00 00 c7 46 10 e0 1f 00 00 48 8b 50 20 <48> 8b 12 0f b7 52 3a 89 56 14 48 8b 40 28 48 8b 00 0f b7 40 58 48 [66303.926722] RSP: 0018:ffffad40472f39c8 EFLAGS: 00010246 [66303.926749] RAX: ffff98a8ada05828 RBX: ffff98a8c46dd060 RCX: ffffad40472f3b48 [66303.926781] RDX: 0000000000000000 RSI: ffff98a8c46dd068 RDI: ffff98a8b23c4000 [66303.926811] RBP: ffffad40472f3b48 R08: 00000000000337b0 R09: 0000000000000000 [66303.926843] R10: 0000000000000001 R11: 0000000000000100 R12: ffff98a8b23c4000 [66303.926874] R13: ffff98a8c46dd060 R14: 000000000000000f R15: ffffad40472f3a50 [66303.926906] FS: 00007f6397966740(0000) GS:ffff98b390900000(0000) knlGS:0000000000000000 [66303.926941] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [66303.926967] CR2: 0000000000000000 CR3: 000000011ac20002 CR4: 00000000007706e0 [66303.926999] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [66303.927029] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [66303.927060] PKRU: 55555554 [66303.927075] Call Trace: [66303.927094] <TASK> [66303.927111] ? __die+0x23/0x70 [66303.927140] ? page_fault_oops+0x171/0x4e0 [66303.927176] ? exc_page_fault+0x7f/0x180 [66303.927209] ? asm_exc_page_fault+0x26/0x30 [66303.927244] ? ice_get_ringparam+0x22/0x50 [ice] [66303.927433] rings_prepare_data+0x62/0x80 [66303.927469] ethnl_default_doit+0xe2/0x350 [66303.927501] genl_family_rcv_msg_doit.isra.0+0xe3/0x140 [66303.927538] genl_rcv_msg+0x1b1/0x2c0 [66303.927561] ? __pfx_ethnl_default_doit+0x10/0x10 [66303.927590] ? __pfx_genl_rcv_msg+0x10/0x10 [66303.927615] netlink_rcv_skb+0x58/0x110 [66303.927644] genl_rcv+0x28/0x40 [66303.927665] netlink_unicast+0x19e/0x290 [66303.927691] netlink_sendmsg+0x254/0x4d0 [66303.927717] sock_sendmsg+0x93/0xa0 [66303.927743] __sys_sendto+0x126/0x170 [66303.927780] __x64_sys_sendto+0x24/0x30 [66303.928593] do_syscall_64+0x5d/0x90 [66303.929370] ? __count_memcg_events+0x60/0xa0 [66303.930146] ? count_memcg_events.constprop.0+0x1a/0x30 [66303.930920] ? handle_mm_fault+0x9e/0x350 [66303.931688] ? do_user_addr_fault+0x258/0x740 [66303.932452] ? exc_page_fault+0x7f/0x180 [66303.933193] entry_SYSCALL_64_after_hwframe+0x72/0xdc

Taxonomy of the tags.




Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Sightings

Author Source Type Date Other

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
