      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mana: Fix double destroy_workqueue on service rescan PCI path\n\nWhile testing corner cases in the driver, a use-after-free crash\nwas found on the service rescan PCI path.\n\nWhen mana_serv_reset() calls mana_gd_suspend(), mana_gd_cleanup()\ndestroys gc->service_wq. If the subsequent mana_gd_resume() fails\nwith -ETIMEDOUT or -EPROTO, the code falls through to\nmana_serv_rescan() which triggers pci_stop_and_remove_bus_device().\nThis invokes the PCI .remove callback (mana_gd_remove), which calls\nmana_gd_cleanup() a second time, attempting to destroy the already-\nfreed workqueue. Fix this by NULL-checking gc->service_wq in\nmana_gd_cleanup() and setting it to NULL after destruction.\n\nCall stack of issue for reference:\n[Sat Feb 21 18:53:48 2026] Call Trace:\n[Sat Feb 21 18:53:48 2026]  <TASK>\n[Sat Feb 21 18:53:48 2026]  mana_gd_cleanup+0x33/0x70 [mana]\n[Sat Feb 21 18:53:48 2026]  mana_gd_remove+0x3a/0xc0 [mana]\n[Sat Feb 21 18:53:48 2026]  pci_device_remove+0x41/0xb0\n[Sat Feb 21 18:53:48 2026]  device_remove+0x46/0x70\n[Sat Feb 21 18:53:48 2026]  device_release_driver_internal+0x1e3/0x250\n[Sat Feb 21 18:53:48 2026]  device_release_driver+0x12/0x20\n[Sat Feb 21 18:53:48 2026]  pci_stop_bus_device+0x6a/0x90\n[Sat Feb 21 18:53:48 2026]  pci_stop_and_remove_bus_device+0x13/0x30\n[Sat Feb 21 18:53:48 2026]  mana_do_service+0x180/0x290 [mana]\n[Sat Feb 21 18:53:48 2026]  mana_serv_func+0x24/0x50 [mana]\n[Sat Feb 21 18:53:48 2026]  process_one_work+0x190/0x3d0\n[Sat Feb 21 18:53:48 2026]  worker_thread+0x16e/0x2e0\n[Sat Feb 21 18:53:48 2026]  kthread+0xf7/0x130\n[Sat Feb 21 18:53:48 2026]  ? __pfx_worker_thread+0x10/0x10\n[Sat Feb 21 18:53:48 2026]  ? __pfx_kthread+0x10/0x10\n[Sat Feb 21 18:53:48 2026]  ret_from_fork+0x269/0x350\n[Sat Feb 21 18:53:48 2026]  ? __pfx_kthread+0x10/0x10\n[Sat Feb 21 18:53:48 2026]  ret_from_fork_asm+0x1a/0x30\n[Sat Feb 21 18:53:48 2026]  </TASK>",
