The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: scsi: sg: Fix slab-use-after-free read     in sg_release() Fix a use-after-free bug in sg_release(), detected by syzbot with KASAN: BUG: KASAN: slab-     use-after-free in lock_release+0x151/0xa30 kernel/locking/lockdep.c:5838
    __mutex_unlock_slowpath+0xe2/0x750 kernel/locking/mutex.c:912 sg_release+0x1f4/0x2e0 drivers/scsi/sg.c:407     In sg_release(), the function kref_put(&sfp->f_ref, sg_remove_sfp) is called before releasing the     open_rel_lock mutex. The kref_put() call may decrement the reference count of sfp to zero, triggering its     cleanup through sg_remove_sfp(). This cleanup includes scheduling deferred work via     sg_remove_sfp_usercontext(), which ultimately frees sfp. After kref_put(), sg_release() continues to     unlock open_rel_lock and may reference sfp or sdp. If sfp has already been freed, this results in a slab-     use-after-free error. Move the kref_put(&sfp->f_ref, sg_remove_sfp) call after unlocking the open_rel_lock     mutex. This ensures: - No references to sfp or sdp occur after the reference count is decremented. -     Cleanup functions such as sg_remove_sfp() and sg_remove_sfp_usercontext() can safely execute without     impacting the mutex handling in sg_release(). The fix has been tested and validated by syzbot. This patch     closes the bug reported at the following syzkaller link and ensures proper sequencing of resource cleanup     and mutex operations, eliminating the risk of use-after-free errors in sg_release(). (CVE-2024-56631)

Note that Nessus relies on the presence of the package as reported by the vendor.
