CVE-2026-74629

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/dibs: Correct freeing of dmb_clientid_arr<br /> <br /> A dibs device interrupt handler can be active after dibs_dev_del() and<br /> may still access dmb_clientid_arr. (UAF)<br /> <br /> In case of a failure in dibs_dev_add() being called by dibs_lo_dev_probe()<br /> dmb_clientid_arr is freed twice (double free).<br /> <br /> Free dmb_clientid_arr in dibs_dev_release() after last reference is gone.<br /> Note that allocating in dibs_dev_add() instead of dibs_dev_alloc() is ok<br /> for now, because no dmbs can be registered before dibs_dev_add().
