Echo: linux: security update to 6.1.170-1

high Tenable Self-Hosted Container Security Plugin ID 465245

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: ksmbd: fix potencial OOB in
 get_file_all_info() for compound requests When a compound request consists of QUERY_DIRECTORY + QUERY_INFO
 (FILE_ALL_INFORMATION) and the first command consumes nearly the entire max_trans_size,
 get_file_all_info() would blindly call smbConvertToUTF16() with PATH_MAX, causing out-of-bounds write
 beyond the response buffer. In get_file_all_info(), there was a missing validation check for the client-
 provided OutputBufferLength before copying the filename into FileName field of the smb2_file_all_info
 structure. If the filename length exceeds the available buffer space, it could lead to potential buffer
 overflows or memory corruption during smbConvertToUTF16 conversion. This calculating the actual free
 buffer size using smb2_calc_max_out_buf_len() and returning -EINVAL if the buffer is insufficient and
 updating smbConvertToUTF16 to use the actual filename length (clamped by PATH_MAX) to ensure a safe copy
 operation. (CVE-2026-31433)

Solution

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