GSD-2021-46914

Vulnerability from gsd - Updated: 2024-02-26 06:03
Details
In the Linux kernel, the following vulnerability has been resolved: ixgbe: fix unbalanced device enable/disable in suspend/resume pci_disable_device() called in __ixgbe_shutdown() decreases dev->enable_cnt by 1. pci_enable_device_mem() which increases dev->enable_cnt by 1, was removed from ixgbe_resume() in commit 6f82b2558735 ("ixgbe: use generic power management"). This caused unbalanced increase/decrease. So add pci_enable_device_mem() back. Fix the following call trace. ixgbe 0000:17:00.1: disabling already-disabled device Call Trace: __ixgbe_shutdown+0x10a/0x1e0 [ixgbe] ixgbe_suspend+0x32/0x70 [ixgbe] pci_pm_suspend+0x87/0x160 ? pci_pm_freeze+0xd0/0xd0 dpm_run_callback+0x42/0x170 __device_suspend+0x114/0x460 async_suspend+0x1f/0xa0 async_run_entry_fn+0x3c/0xf0 process_one_work+0x1dd/0x410 worker_thread+0x34/0x3f0 ? cancel_delayed_work+0x90/0x90 kthread+0x14c/0x170 ? kthread_park+0x90/0x90 ret_from_fork+0x1f/0x30
