{"id":"AZL-104546","summary":"CVE-2026-97948 affecting package kernel 6.6.157.1-1","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[\u003c0\u003e] 0xc00000011c78f870\n[\u003c0\u003e] __switch_to+0xfc/0x1a0\n[\u003c0\u003e] pci_lock_rescan_remove+0x30/0x44\n[\u003c0\u003e] eeh_rmv_device+0x290/0x2e0\n[\u003c0\u003e] eeh_pe_dev_traverse+0x80/0x130\n[\u003c0\u003e] eeh_reset_device+0xcc/0x23c\n[\u003c0\u003e] eeh_handle_normal_event+0x830/0xa80\n[\u003c0\u003e] eeh_event_handler+0xf8/0x190\n[\u003c0\u003e] kthread+0x194/0x1b0\n[\u003c0\u003e] start_kernel_thread+0x14/0x18\n\nThe issue is seen for cases where the errors are detected on the PHB\ndirectly AND|OR for devices where 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).","modified":"2026-09-27T05:34:32Z","published":"2026-09-25T11:17:22Z","upstream":["CVE-2026-97948"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97948"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-104546.json"}}],"schema_version":"1.9.0"}
