  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/panthor: validate userspace queue count against initialized firmware slot count  In panthor_drv.c:panthor_ioctl_group_create(), the queue count is validated against the hardcoded maximum:  \tif (!args-\u003Equeues.count || args-\u003Equeues.count \u003E MAX_CS_PER_CSG) \t\treturn -EINVAL;  However, if the firmware reports fewer slots than MAX_CS_PER_CSG, panthor_fw_init_ifaces() will only initialize that smaller number of stream interfaces.  If unprivileged userspace requests more queues than the firmware reported (but no more than MAX_CS_PER_CSG), cs_slot_prog_locked() fetches an uninitialized stream interface and may crash when dereferencing cs_iface-\u003Einput-\u003Eringbuf_base.",
