Echo: linux: security update to 6.1.153-1

medium Tenable Cloud Security Plugin ID 463616

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: libiscsi: Initialize
 iscsi_conn->dd_data only if memory is allocated In case of an ib_fast_reg_mr allocation failure during
 iSER setup, the machine hits a panic because iscsi_conn->dd_data is initialized unconditionally, even when
 no memory is allocated (dd_size == 0). This leads invalid pointer dereference during connection teardown.
 Fix by setting iscsi_conn->dd_data only if memory is actually allocated. Panic trace: ------------ iser:
 iser_create_fastreg_desc: Failed to allocate ib_fast_reg_mr err=-12 iser: iser_alloc_rx_descriptors:
 failed allocating rx descriptors / data buffers BUG: unable to handle page fault for address:
