Echo: linux: security update to 6.1.170-1

high Tenable Cloud Security Plugin ID 463925

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: erofs: add GFP_NOIO in the bio
 completion if needed The bio completion path in the process context (e.g. dm-verity) will directly call
 into decompression rather than trigger another workqueue context for minimal scheduling latencies, which
 can then call vm_map_ram() with GFP_KERNEL. Due to insufficient memory, vm_map_ram() may generate memory
 swapping I/O, which can cause submit_bio_wait to deadlock in some scenarios. Trimmed down the call stack,
 as follows: f2fs_submit_read_io submit_bio //bio_list is initialized. mmc_blk_mq_recovery z_erofs_endio
 vm_map_ram __pte_alloc_kernel __alloc_pages_direct_reclaim shrink_folio_list __swap_writepage
 submit_bio_wait //bio_list is non-NULL, hang!!! Use memalloc_noio_{save,restore}() to wrap up this path.
 (CVE-2026-31467)

Solution

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