CVE-2026-74265

Estado: RecibidaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

net: mana: initialize gdma queue id to INVALID_QUEUE_ID

mana_gd_create_mana_wq_cq() leaves queue->id as 0 (from kzalloc_obj()) until mana_create_wq_obj() assigns the firmware-returned id. If creation fails before that, cleanup calls mana_gd_destroy_cq() with id 0, NULLing gc->cq_table[0] and silently breaking whichever real CQ owns that slot.

Initialize queue->id to INVALID_QUEUE_ID right after allocation, matching mana_gd_create_eq(). The existing (id >= max_num_cqs) guard then short-circuits cleanly.
