Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 458761

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: usb: gadget: f_mass_storage: Fix
 potential integer overflow in check_command_size_in_blocks() The `check_command_size_in_blocks()` function
 calculates the data size in bytes by left shifting `common->data_size_from_cmnd` by the block size
 (`common->curlun->blkbits`). However, it does not validate whether this shift operation will cause an
 integer overflow. Initially, the block size is set up in `fsg_lun_open()` , and the
 `common->data_size_from_cmnd` is set up in `do_scsi_command()`. During initialization, there is no integer
 overflow check for the interaction between two variables. So if a malicious USB host sends a SCSI READ or
 WRITE command requesting a large amount of data (`common->data_size_from_cmnd`), the left shift operation
 can wrap around. This results in a truncated data size, which can bypass boundary checks and potentially
 lead to memory corruption or out-of-bounds accesses. Fix this by using the check_shl_overflow() macro to
 safely perform the shift and catch any overflows. (CVE-2026-31412)

Solution

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