Specifically,\neeh_handle_normal_event() acquired pci_lock_rescan_remove() before\ncalling eeh_pe_bus_get(), but eeh_pe_bus_get() itself attempts to\nacquire the same lock internally, causing nested locking and disrupting\nnormal EEH event handling paths.\n\nThis patch adds a boolean parameter do_lock to _eeh_pe_bus_get(),\nwith two public wrappers:\n eeh_pe_bus_get() with locking enabled.\n eeh_pe_bus_get_nolock() that skips locking.\n\nCallers that already hold pci_lock_rescan_remove() now use\neeh_pe_bus_get_nolock() to avoid recursive lock acquisition.\n\nAdditionally, pci_lock_rescan_remove() calls are restored to the correct\nposition\u2014after eeh_pe_bus_get() and immediately before iterating affected\nPEs and devices. This ensures EEH-triggered PCI removes occur under proper\nbus rescan locking without recursive lock contention.\n\nThe eeh_pe_loc_get() function has been split into two functions:\n eeh_pe_loc_get(struct eeh_pe *pe) which retrieves the loc for given PE.\n eeh_pe_loc_get_bus(struct pci_bus *bus) which retrieves the location\n code for given bus.\n\nThis resolves lockdep warnings such as:\n<snip>\n[ 84.964298] [ T928] ============================================\n[ 84.964304] [ T928] WARNING: possible recursive locking detected\n[ 84.964311] [ T928] 6.18.0-rc3 #51 Not tainted\n[ 84.964315] [ T928] --------------------------------------------\n[ 84.964320] [ T928] eehd/928 is trying to acquire lock:\n[ 84.964324] [ T928] c000000003b29d58 (pci_rescan_remove_lock){+.+.}-{3:3}, at: pci_lock_rescan_remove+0x28/0x40\n[ 84.964342] [ T928]\n but task is already holding lock:\n[ 84.964347] [ T928] c000000003b29d58 (pci_rescan_remove_lock){+.+.}-{3:3}, at: pci_lock_rescan_remove+0x28/0x40\n[ 84.964357] [ T928]\n other info that might help us debug this:\n[ 84.964363] [ T928] Possible unsafe locking scenario:\n\n[ 84.964367] [ T928] CPU0\n[ 84.964370] [ T928] ----\n[ 84.964373] [ T928] lock(pci_rescan_remove_lock);\n[ 84.964378] [ T928] lock(pci_rescan_remove_lock);\n[ 84.964383] [ T928]\n *** DEADLOCK ***\n\n[ 84.964388] [ T928] May be due to missing lock nesting notation\n\n[ 84.964393] [ T928] 1 lock held by eehd/928:\n[ 84.964397] [ T928] #0: c000000003b29d58 (pci_rescan_remove_lock){+.+.}-{3:3}, at: pci_lock_rescan_remove+0x28/0x40\n[ 84.964408] [ T928]\n stack backtrace:\n[ 84.964414] [ T928] CPU: 2 UID: 0 PID: 928 Comm: eehd Not tainted 6.18.0-rc3 #51 VOLUNTARY\n[ 84.964417] [ T928] Hardware name: IBM,9080-HEX POWER10 (architected) 0x800200 0xf000006 of:IBM,FW1060.00 (NH1060_022) hv:phyp pSeries\n[ 84.964419] [ T928] Call Trace:\n[ 84.964420] [ T928] [c0000011a7157990] [c000000001705de4] dump_stack_lvl+0xc8/0x130 (unreliable)\n[ 84.964424] [ T928] [c0000011a71579d0] [c0000000002f66e0] print_deadlock_bug+0x430/0x440\n[ 84.964428] [ T928] [c0000011a7157a70] [c0000000002fd0c0] __lock_acquire+0x1530/0x2d80\n[ 84.964431] [ T928] [c0000011a7157ba0] [c0000000002fea54] lock_acquire+0x144/0x410\n[ 84.964433] [ T928] [c0000011a7157cb0] [c0000011a7157cb0] __mutex_lock+0xf4/0x1050\n[ 84.964436] [ T928] [c0000011a7157e00] [c000000000de21d8] pci_lock_rescan_remove+0x28/0x40\n[ 84.964439] [ T928] [c0000011a7157e20] [c00000000004ed98] eeh_pe_bus_get+0x48/0xc0\n[ 84.964442] [ T928] [c0000011a7157e50] [c00000\n---truncated---"}], "id": "CVE-2026-45904", "lastModified": "2026-06-17T10:52:42.190", "metrics": {}, "published": "2026-05-27T14:17:04.820", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/6e6561231c6cfc32c5631aeecc0928ff2b14265c"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/788dd28fd49610d6047cbb15dbf1186afffdfbaf"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/815a8d2feb5615ae7f0b5befd206af0b0160614c"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/87a1f93986aa1500b85aeff16b0b71c29ea116ea"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/89810e2d80281d42f855fac813786758ee16e323"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/b85ee287bfe52c6b2d9b41758b5e0d08679d5b39"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/f49faa4a64f8ac0e38983e606075b25dfcfc9ad4"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/f8b16d5764ee1e78c1ef333017ad383ffe76fcdc"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Awaiting Analysis"}
