{"schema":"threatline.record/2","record":{"id":"CVE-2026-98217","aliases":[],"summary":"IB/mlx4: Fix use-after-free on pkey sysfs registration failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nIB/mlx4: Fix use-after-free on pkey sysfs registration failure\n\nregister_pkey_tree() ignores errors from register_one_pkey_tree() and\ncontinues registering the remaining slaves. The per-slave error path has\nalready released the pkey parent kobjects, but their pointers remain\nstored in the device. A later device cleanup therefore passes the stale\npointers to kobject_put(), causing a use-after-free.\n\nClear the parent pointers after releasing a failed slave tree and skip\nunregistered trees during device cleanup. This preserves the existing\nbest-effort registration behavior while preventing a second cleanup of\nthe failed tree.","categories":["Operating
