CVE-2026-23162

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/xe/nvm: Fix double-free on aux add failure<br /> <br /> After a successful auxiliary_device_init(), aux_dev-&gt;dev.release<br /> (xe_nvm_release_dev()) is responsible for the kfree(nvm). When<br /> there is failure with auxiliary_device_add(), driver will call<br /> auxiliary_device_uninit(), which call put_device(). So that the<br /> .release callback will be triggered to free the memory associated<br /> with the auxiliary_device.<br /> <br /> Move the kfree(nvm) into the auxiliary_device_init() failure path<br /> and remove the err goto path to fix below error.<br /> <br /> "<br /> [ 13.232905] ==================================================================<br /> [ 13.232911] BUG: KASAN: double-free in xe_nvm_init+0x751/0xf10 [xe]<br /> [ 13.233112] Free of addr ffff888120635000 by task systemd-udevd/273<br /> <br /> [ 13.233120] CPU: 8 UID: 0 PID: 273 Comm: systemd-udevd Not tainted 6.19.0-rc2-lgci-xe-kernel+ #225 PREEMPT(voluntary)<br /> ...<br /> [ 13.233125] Call Trace:<br /> [ 13.233126] <br /> [ 13.233127] dump_stack_lvl+0x7f/0xc0<br /> [ 13.233132] print_report+0xce/0x610<br /> [ 13.233136] ? kasan_complete_mode_report_info+0x5d/0x1e0<br /> [ 13.233139] ? xe_nvm_init+0x751/0xf10 [xe]<br /> ...<br /> "<br /> <br /> v2: drop err goto path.
