medium Tenable Self-Hosted Container Security Plugin ID 463315

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix the recovery flow of
 the UMR QP This patch addresses an issue in the recovery flow of the UMR QP, ensuring tasks do not get
 stuck, as highlighted by the call trace [1]. During recovery, before transitioning the QP to the RESET
 state, the software must wait for all outstanding WRs to complete. Failing to do so can cause the firmware
 to skip sending some flushed CQEs with errors and simply discard them upon the RESET, as per the IB
 specification. This race condition can result in lost CQEs and tasks becoming stuck. To resolve this, the
 patch sends a final WR which serves only as a barrier before moving the QP state to RESET. Once a CQE is
 received for that final WR, it guarantees that no outstanding WRs remain, making it safe to transition the
 QP to RESET and subsequently back to RTS, restoring proper functionality. Note: For the barrier WR, we
 simply reuse the failed and ready WR. Since the QP is in an error state, it will only receive
 IB_WC_WR_FLUSH_ERR. However, as it serves only as a barrier we don't care about its status. [1] INFO: task
 rdma_resource_l:1922 blocked for more than 120 seconds. Tainted: G W 6.12.0-rc7+ #1626 "echo 0 >
