Published May 28, 2026
·
Updated

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

RDMA/mana: Fix manadestroywqobj() cleanup in manaibcreateqprss()

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 manaibinstallcqcb() fails then manacreatewqobj() is not undone due to the above i--.
