Echo: linux: security update to 6.1.159-1

high Tenable Cloud Security Plugin ID 457892

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: net: ethernet: ti: netcp: Standardize
 knav_dma_open_channel to return NULL on error Make knav_dma_open_channel consistently return NULL on error
 instead of ERR_PTR. Currently the header include/linux/soc/ti/knav_dma.h returns NULL when the driver is
 disabled, but the driver implementation does not even return NULL or ERR_PTR on failure, causing
 inconsistency in the users. This results in a crash in netcp_free_navigator_resources as followed
 (trimmed): Unhandled fault: alignment exception (0x221) at 0xfffffff2 [fffffff2] *pgd=80000800207003,

 Standardize the error handling by making the function return NULL on all error conditions. The API is used
 in just the netcp_core.c so the impact is limited. Note, this change, in effect reverts commit
 5b6cb43b4d62 ("net: ethernet: ti: netcp_core: return error while dma channel open issue"), but provides a
 less error prone implementation. (CVE-2025-68220)

Solution

Update the linux library and its related packages to version 6.1.159-1 or later.
