Echo: linux: security update to 6.1.176-1

medium Tenable Self-Hosted Container Security Plugin ID 460107

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: ALSA: control: Validate buf_len before
 strnlen() in snd_ctl_elem_init_enum_names() snd_ctl_elem_init_enum_names() advances pointer p through the
 names buffer while decrementing buf_len. If buf_len reaches zero but items remain, the next iteration
 calls strnlen(p, 0). While strnlen(p, 0) returns 0 and would hit the existing name_len == 0 error path,
 CONFIG_FORTIFY_SOURCE's fortified strnlen() first checks maxlen against __builtin_dynamic_object_size().
 When Clang loses track of p's object size inside the loop, this triggers a BRK exception panic before the
 return value is examined. Add a buf_len == 0 guard at the loop entry to prevent calling fortified
 strnlen() on an exhausted buffer. Found by kernel fuzz testing through Xiaomi Smartphone. (CVE-2026-46088)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
