Echo: linux: security update to 6.1.158-1

high Tenable Self-Hosted Container Security Plugin ID 455360

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: scsi: target: target_core_configfs:
 Add length check to avoid buffer overflow A buffer overflow arises from the usage of snprintf to write
 into the buffer "buf" in target_lu_gp_members_show function located in
 /drivers/target/target_core_configfs.c. This buffer is allocated with size LU_GROUP_NAME_BUF (256 bytes).
 snprintf(...) formats multiple strings into buf with the HBA name (hba->hba_group.cg_item), a slash
 character, a devicename (dev-> dev_group.cg_item) and a newline character, the total formatted string
 length may exceed the buffer size of 256 bytes. Since snprintf() returns the total number of bytes that
 would have been written (the length of %s/%sn ), this value may exceed the buffer length (256 bytes)
 passed to memcpy(), this will ultimately cause function memcpy reporting a buffer overflow error. An
 additional check of the return value of snprintf() can avoid this buffer overflow. (CVE-2025-39998)

Solution

Update the linux library and its related packages to version 6.1.158-1 or later.
