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: Wake up the error handler
when final completions race against each other The fragile ordering between marking commands completed or
failed so that the error handler only wakes when the last running command completes or times out has race
conditions. These race conditions can cause the SCSI layer to fail to wake the error handler, leaving I/O
through the SCSI host stuck as the error state cannot advance. First, there is an memory ordering issue
within scsi_dec_host_busy(). The write which clears SCMD_STATE_INFLIGHT may be reordered with reads
counting in scsi_host_busy(). While the local CPU will see its own write, reordering can allow other CPUs
in scsi_dec_host_busy() or scsi_eh_inc_host_failed() to see a raised busy count, causing no CPU to see a
host busy equal to the host_failed count. This race condition can be prevented with a memory barrier on
the error path to force the write to be visible before counting host busy commands. Second, there is a
general ordering issue with scsi_eh_inc_host_failed(). By counting busy commands before incrementing
host_failed, it can race with a final command in scsi_dec_host_busy(), such that scsi_dec_host_busy() does
not see host_failed incremented but scsi_eh_inc_host_failed() counts busy commands before
SCMD_STATE_INFLIGHT is cleared by scsi_dec_host_busy(), resulting in neither waking the error handler
task. This needs the call to scsi_host_busy() to be moved after host_failed is incremented to close the
race condition. (CVE-2026-23110)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.534.2 or later.
