{"id":"CVE-2026-23162","summary":"drm/xe/nvm: Fix double-free on aux add failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe/nvm: Fix double-free on aux add failure\n\nAfter a successful auxiliary_device_init(), aux_dev-\u003edev.release\n(xe_nvm_release_dev()) is responsible for the kfree(nvm). When\nthere is failure with auxiliary_device_add(), driver will call\nauxiliary_device_uninit(), which call put_device(). So that the\n.release callback will be triggered to free the memory associated\nwith the auxiliary_device.\n\nMove the kfree(nvm) into the auxiliary_device_init() failure path\nand remove the err goto path to fix below error.\n\n\"\n[   13.232905] ==================================================================\n[   13.232911] BUG: KASAN: double-free in xe_nvm_init+0x751/0xf10 [xe]\n[   13.233112] Free of addr ffff888120635000 by task systemd-udevd/273\n\n[   13.233120] CPU: 8 UID: 0 PID: 273 Comm: systemd-udevd Not tainted 6.19.0-rc2-lgci-xe-kernel+ #225 PREEMPT(voluntary)\n...\n[   13.233125] Call Trace:\n[   13.233126]  \u003cTASK\u003e\n[   13.233127]  dump_stack_lvl+0x7f/0xc0\n[   13.233132]  print_report+0xce/0x610\n[   13.233136]  ? kasan_complete_mode_report_info+0x5d/0x1e0\n[   13.233139]  ? xe_nvm_init+0x751/0xf10 [xe]\n...\n\"\n\nv2: drop err goto path.
