"value": "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->dev.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] <TASK>\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.
