CVE-2026-46117 RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()

In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Remove user triggerable WARNON in manaibcreateqprss Sashiko points out that the user can specify WQs sharing the same CQ as a part of the uAPI and this will trigger the WARNON then go on to corrupt the kernel. Just...

SUSE CVE-2026-46084

In the Linux kernel, the following vulnerability has been resolved: RDMA/manaib: Disable RX steering on RSS QP destroy When an RSS QP is destroyed e.g. DPDK exit, manaibdestroyqprss destroys the RX WQ objects but does not disable vPort RX steering in firmware. This leaves stale steering...
