  "title": "linux: In the Linux kernel, the following vulnerability has been resolved:  pds_core: Fix pdsc_check_pci_health function to...",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  pds_core: Fix pdsc_check_pci_health function to use work thread  When the driver notices fw_status == 0xff it tries to perform a PCI reset on itself via pci_reset_function() in the context of the driver\u0027s health thread. However, pdsc_reset_prepare calls pdsc_stop_health_thread(), which attempts to stop/flush the health thread. This results in a deadlock because the stop/flush will never complete since the driver called pci_reset_function() from the health thread context. Fix by changing the pdsc_check_pci_health_function() to queue a newly introduced pdsc_pci_reset_thread() on the pdsc\u0027s work queue.  Unloading the driver in the fw_down/dead state uncovered another issue, which can be seen in the following trace:  WARNING: CPU: 51 PID: 6914 at kernel/workqueue.c:1450 __queue_work\u002B0x358/0x440 [...] RIP: 0010:__queue_work\u002B0x358/0x440 [...] Call Trace:  \u003CTASK\u003E  ? __warn\u002B0x85/0x140  ? __queue_work\u002B0x358/0x440  ? report_bug\u002B0xfc/0x1e0  ? handle_bug\u002B0x3f/0x70  ? exc_invalid_op\u002B0x17/0x70  ? asm_exc_invalid_op\u002B0x1a/0x20  ? __queue_work\u002B0x358/0x440  queue_work_on\u002B0x28/0x30  pdsc_devcmd_locked\u002B0x96/0xe0 [pds_core]  pdsc_devcmd_reset\u002B0x71/0xb0 [pds_core]  pdsc_teardown\u002B0x51/0xe0 [pds_core]  pdsc_remove\u002B0x106/0x200 [pds_core]  pci_device_remove\u002B0x37/0xc0  device_release_driver_internal\u002B0xae/0x140  driver_detach\u002B0x48/0x90  bus_remove_driver\u002B0x6d/0xf0  pci_unregister_driver\u002B0x2e/0xa0  pdsc_cleanup_module\u002B0x10/0x780 [pds_core]  __x64_sys_delete_module\u002B0x142/0x2b0  ? syscall_trace_enter.isra.18\u002B0x126/0x1a0  do_syscall_64\u002B0x3b/0x90  entry_SYSCALL_64_after_hwframe\u002B0x72/0xdc RIP: 0033:0x7fbd9d03a14b [...]  Fix this by preventing the devcmd reset if the FW is not running.",
