CVE-2026-46126 Details
Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Fix mana_destroy_wq_obj() cleanup in mana_ib_create_qp_rss() Sashiko points out there are two bugs here in the error unwind flow, both related to how the WQ table is unwound. First there is a double i-- on the first failure path due to the while loop having a i--, remove it. Second if mana_ib_install_cq_cb() fails then mana_create_wq_obj() is not undone due to the above i--.
A vulnerability exists in the Linux kernel's RDMA Mana component, specifically within the 'mana_ib_create_qp_rss' function. This issue arises from improper error handling during the creation of queue pairs, which can lead to resource leaks. When 'mana_ib_install_cq_cb' fails, the corresponding work queue object is not properly cleaned up, causing potential inconsistencies. This vulnerability affects the stable version of the Linux kernel.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
