Google: sys-kernel/lakitu-kernel-6_1: security update to 18244.1.7

medium Tenable Self-Hosted Container Security Plugin ID 451420

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: scsi: core: Move scsi_host_busy() out
of host lock for waking up EH handler Inside scsi_eh_wakeup(), scsi_host_busy() is called & checked with
host lock every time for deciding if error handler kthread needs to be waken up. This can be too heavy in
case of recovery, such as: - N hardware queues - queue depth is M for each hardware queue - each
scsi_host_busy() iterates over (N * M) tag/requests If recovery is triggered in case that all requests are
in-flight, each scsi_eh_wakeup() is strictly serialized, when scsi_eh_wakeup() is called for the last in-
flight request, scsi_host_busy() has been run for (N * M - 1) times, and request has been iterated for
(N*M - 1) * (N * M) times. If both N and M are big enough, hard lockup can be triggered on acquiring host
lock, and it is observed on mpi3mr(128 hw queues, queue depth 8169). Fix the issue by calling
scsi_host_busy() outside the host lock. We don't need the host lock for getting busy count because host
the lock never covers that. [mkp: Drop unnecessary 'busy' variables pointed out by Bart] (CVE-2024-26627)
