{"schema":"threatline.record/2","record":{"id":"CVE-2026-97948","aliases":[],"summary":"powerpc/eeh: Fix recursive locking on devices without EEH sensitive driver","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npowerpc/eeh: Fix recursive locking on devices without EEH sensitive driver\n\nThe commit 1010b4c012b0 (\"powerpc/eeh: Make EEH driver device hotplug\nsafe\") refactored the EEH code such that the pci_rescan_remove_lock is\nheld at the beginning of eeh_handle_normal_event() and the\neeh_reset_device() is called with that lock being held. Looks like the\ncommit missed to remove the existing lock/unlock inside eeh_rmv_device()\nwhich is no longer necessary. This is causing the eehd to hang on the\nlock which it actually holds when that code path is taken.\n\n[<0>] 0xc00000011c78f870\n[<0>] __switch_to+0xfc/0x1a0\n[<0>]

the driver error_detected() returns\nPCI_ERS_RESULT_NEED_RESET, and driver being not EEH sensitive(i.e no\nerror handlers like slot_reset(), resume() etc defined).","categories":["Operating
