Echo: linux: security update to 6.12.63-1

medium Tenable Cloud Security Plugin ID 460392

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: imm: Fix use-after-free bug
 caused by unfinished delayed work The delayed work item 'imm_tq' is initialized in imm_attach() and
 scheduled via imm_queuecommand() for processing SCSI commands. When the IMM parallel port SCSI host
 adapter is detached through imm_detach(), the imm_struct device instance is deallocated. However, the
 delayed work might still be pending or executing when imm_detach() is called, leading to use-after-free
 bugs when the work function imm_interrupt() accesses the already freed imm_struct memory. The race
 condition can occur as follows: CPU 0(detach thread) | CPU 1 | imm_queuecommand() | imm_queuecommand_lck()
 imm_detach() | schedule_delayed_work() kfree(dev) //FREE | imm_interrupt() | dev = container_of(...) //USE
 dev-> //USE Add disable_delayed_work_sync() in imm_detach() to guarantee proper cancellation of the
 delayed work item before imm_struct is deallocated. (CVE-2025-68324)

Solution

Update the linux library and its related packages to version 6.12.63-1 or later.
