medium Tenable Self-Hosted Container Security Plugin ID 468877

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 eh reliably when
using scsi_schedule_eh Drivers which use the scsi_schedule_eh function to run the error handler currently
risk the error handler thread never waking once all commands are timed out or inactive. There is no
enforced memory order between setting the host into error recovery state and counting busy commands. This
can result in a race with scsi_dec_host_busy where neither CPU sees both conditions of all commands
inactive and the host error state to request waking the error handler. To fix this, run the
scsi_schedule_eh's scsi_eh_wakeup from a new work item which will use rcu to ensure scsi_schedule_eh's
call to scsi_host_busy will occur after the error state is globally visible and will be seen by any
current scsi_dec_host_busy callers. (CVE-2026-68396)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.299.137 or later.
