Echo: linux: security update to 6.1.153-1

high Tenable Cloud Security Plugin ID 460357

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: drbd: add missing kref_get in
 handle_write_conflicts With `two-primaries` enabled, DRBD tries to detect "concurrent" writes and handle
 write conflicts, so that even if you write to the same sector simultaneously on both nodes, they end up
 with the identical data once the writes are completed. In handling "superseeded" writes, we forgot a
 kref_get, resulting in a premature drbd_destroy_device and use after free, and further to kernel crashes
 with symptoms. Relevance: No one should use DRBD as a random data generator, and apparently all users of
 "two-primaries" handle concurrent writes correctly on layer up. That is cluster file systems use some
 distributed lock manager, and live migration in virtualization environments stops writes on one node
 before starting writes on the other node. Which means that other than for "test cases", this code path is
 never taken in real life. FYI, in DRBD 9, things are handled differently nowadays. We still detect "write
 conflicts", but no longer try to be smart about them. We decided to disconnect hard instead: upper layers
 must not submit concurrent writes. If they do, that's their fault. (CVE-2025-38708)

Solution

Update the linux library and its related packages to version 6.1.153-1 or later.
