Title
net/mlx5: LAG, fix logic over MLX5_LAG_FLAG_NDEVS_READY
Summary
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: LAG, fix logic over MLX5_LAG_FLAG_NDEVS_READY Only set MLX5_LAG_FLAG_NDEVS_READY if both netdevices are registered. Doing so guarantees that both ldev->pf[MLX5_LAG_P0].dev and ldev->pf[MLX5_LAG_P1].dev have valid pointers when MLX5_LAG_FLAG_NDEVS_READY is set. The core issue is asymmetry in setting MLX5_LAG_FLAG_NDEVS_READY and clearing it. Setting it is done wrongly when both ldev->pf[MLX5_LAG_P0].dev and ldev->pf[MLX5_LAG_P1].dev are set; clearing it is done right when either of ldev->pf[i].netdev is cleared. Consider the following scenario: 1. PF0 loads and sets ldev->pf[MLX5_LAG_P0].dev to a valid pointer 2. PF1 loads and sets both ldev->pf[MLX5_LAG_P1].dev and ldev->pf[MLX5_LAG_P1].netdev with valid pointers. This results in MLX5_LAG_FLAG_NDEVS_READY is set. 3. PF0 is unloaded before setting dev->pf[MLX5_LAG_P0].netdev. MLX5_LAG_FLAG_NDEVS_READY remains set. Further execution of mlx5_do_bond() will result in null pointer dereference when calling mlx5_lag_is_multipath() This patch fixes the following call trace actually encountered: [ 1293.475195] BUG: kernel NULL pointer dereference, address: 00000000000009a8 [ 1293.478756] #PF: supervisor read access in kernel mode [ 1293.481320] #PF: error_code(0x0000) - not-present page [ 1293.483686] PGD 0 P4D 0 [ 1293.484434] Oops: 0000 [#1] SMP PTI [ 1293.485377] CPU: 1 PID: 23690 Comm: kworker/u16:2 Not tainted 5.18.0-rc5_for_upstream_min_debug_2022_05_05_10_13 #1 [ 1293.488039] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014 [ 1293.490836] Workqueue: mlx5_lag mlx5_do_bond_work [mlx5_core] [ 1293.492448] RIP: 0010:mlx5_lag_is_multipath+0x5/0x50 [mlx5_core] [ 1293.494044] Code: e8 70 40 ff e0 48 8b 14 24 48 83 05 5c 1a 1b 00 01 e9 19 ff ff ff 48 83 05 47 1a 1b 00 01 eb d7 0f 1f 44 00 00 0f 1f 44 00 00 <48> 8b 87 a8 09 00 00 48 85 c0 74 26 48 83 05 a7 1b 1b 00 01 41 b8 [ 1293.498673] RSP: 0018:ffff88811b2fbe40 EFLAGS: 00010202 [ 1293.500152] RAX: ffff88818a94e1c0 RBX: ffff888165eca6c0 RCX: 0000000000000000 [ 1293.501841] RDX: 0000000000000001 RSI: ffff88818a94e1c0 RDI: 0000000000000000 [ 1293.503585] RBP: 0000000000000000 R08: ffff888119886740 R09: ffff888165eca73c [ 1293.505286] R10: 0000000000000018 R11: 0000000000000018 R12: ffff88818a94e1c0 [ 1293.506979] R13: ffff888112729800 R14: 0000000000000000 R15: ffff888112729858 [ 1293.508753] FS: 0000000000000000(0000) GS:ffff88852cc40000(0000) knlGS:0000000000000000 [ 1293.510782] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 1293.512265] CR2: 00000000000009a8 CR3: 00000001032d4002 CR4: 0000000000370ea0 [ 1293.514001] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 1293.515806] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400

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.

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.
