Echo: linux: security update to 6.1.162-1

medium Tenable Self-Hosted Container Security Plugin ID 459897

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: vsock/virtio: fix potential underflow
 in virtio_transport_get_credit() The credit calculation in virtio_transport_get_credit() uses unsigned
 arithmetic: ret = vvs->peer_buf_alloc - (vvs->tx_cnt - vvs->peer_fwd_cnt); If the peer shrinks its
 advertised buffer (peer_buf_alloc) while bytes are in flight, the subtraction can underflow and produce a
 large positive value, potentially allowing more data to be queued than the peer can handle. Reuse
 virtio_transport_has_space() which already handles this case and add a comment to make it clear why we are
 doing that. [Stefano: use virtio_transport_has_space() instead of duplicating the code] [Stefano: tweak
 the commit message] (CVE-2026-23069)

Solution

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