Echo: linux: security update to 6.11.4-1

medium Tenable Cloud Security Plugin ID 459892

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: x86/mm/ident_map: Use gbpages only
 where full GB page should be mapped. When ident_pud_init() uses only GB pages to create identity maps,
 large ranges of addresses not actually requested can be included in the resulting table; a 4K request will
 map a full GB. This can include a lot of extra address space past that requested, including areas marked
 reserved by the BIOS. That allows processor speculation into reserved regions, that on UV systems can
 cause system halts. Only use GB pages when map creation requests include the full GB page of space. Fall
 back to using smaller 2M pages when only portions of a GB page are included in the request. No attempt is
 made to coalesce mapping requests. If a request requires a map entry at the 2M (pmd) level, subsequent
 mapping requests within the same 1G region will also be at the pmd level, even if adjacent or overlapping
 such requests could have been combined to map a full GB page. Existing usage starts with larger regions
 and then adds smaller regions, so this should not have any great consequence. (CVE-2024-50017)

Solution

Update the linux library and its related packages to version 6.11.4-1 or later.
