Description
In the Linux kernel, the following vulnerability has been resolved:
pds_core: remove write-after-free of client_id
A use-after-free error popped up in stress testing:
[Mon Apr 21 21:21:33 2025] BUG: KFENCE: use-after-free write in pdsc_auxbus_dev_del+0xef/0x160 [pds_core]
[Mon Apr 21 21:21:33 2025] Use-after-free write at 0x000000007013ecd1 (in kfence-#47):
[Mon Apr 21 21:21:33 2025] pdsc_auxbus_dev_del+0xef/0x160 [pds_core]
[Mon Apr 21 21:21:33 2025] pdsc_remove+0xc0/0x1b0 [pds_core]
[Mon Apr 21 21:21:33 2025] pci_device_remove+0x24/0x70
[Mon Apr 21 21:21:33 2025] device_release_driver_internal+0x11f/0x180
[Mon Apr 21 21:21:33 2025] driver_detach+0x45/0x80
[Mon Apr 21 21:21:33 2025] bus_remove_driver+0x83/0xe0
[Mon Apr 21 21:21:33 2025] pci_unregister_driver+0x1a/0x80
The actual device uninit usually happens on a separate thread
scheduled after this code runs, but there is no guarantee of order
of thread execution, so this could be a problem. There's no
actual need to clear the client_id at this point, so simply
remove the offending code.
