Echo: linux: security update to 6.1.162-1

medium Tenable Cloud Security Plugin ID 455517

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: libceph: make calc_target() set
 t->paused, not just clear it Currently calc_target() clears t->paused if the request shouldn't be paused
 anymore, but doesn't ever set t->paused even though it's able to determine when the request should be
 paused. Setting t->paused is left to __submit_request() which is fine for regular requests but doesn't
 work for linger requests -- since __submit_request() doesn't operate on linger requests, there is nowhere
 for lreq->t.paused to be set. One consequence of this is that watches don't get reestablished on paused ->
 unpaused transitions in cases where requests have been paused long enough for the (paused) unwatch request
 to time out and for the subsequent (re)watch request to enter the paused state. On top of the watch not
 getting reestablished, rbd_reregister_watch() gets stuck with rbd_dev->watch_mutex held:
 rbd_register_watch __rbd_register_watch ceph_osdc_watch linger_reg_commit_wait It's waiting for
 lreq->reg_commit_wait to be completed, but for that to happen the respective request needs to end up on
 need_resend_linger list and be kicked when requests are unpaused. There is no chance for that if the
 request in question is never marked paused in the first place. The fact that rbd_dev->watch_mutex remains
 taken out forever then prevents the image from getting unmapped -- "rbd unmap" would inevitably hang in D
 state on an attempt to grab the mutex. (CVE-2026-23047)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
