Echo: linux: security update to 6.1.170-1

critical Tenable Self-Hosted Container Security Plugin ID 458681

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: media: dvb-net: fix OOB access in ULE
 extension header tables The ule_mandatory_ext_handlers[] and ule_optional_ext_handlers[] tables in
 handle_one_ule_extension() are declared with 255 elements (valid indices 0-254), but the index htype is
 derived from network-controlled data as (ule_sndu_type & 0x00FF), giving a range of 0-255. When htype
 equals 255, an out-of-bounds read occurs on the function pointer table, and the OOB value may be called as
 a function pointer. Add a bounds check on htype against the array size before either table is accessed.
 Out-of-range values now cause the SNDU to be discarded. (CVE-2026-31405)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
