Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 462728

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: serial: io_ti: fix heap overflow
 in build_i2c_fw_hdr() build_i2c_fw_hdr() allocates a fixed-size buffer of (16*1024 - 512) + sizeof(struct
 ti_i2c_firmware_rec) bytes, then copies le16_to_cpu(img_header->Length) bytes into it without validating
 that Length fits within the available space after the firmware record header. img_header->Length is a
 __le16 from the firmware file and can be up to 65535. check_fw_sanity() validates the total firmware size
 but not img_header->Length specifically. Fix by rejecting images where img_header->Length exceeds the
 available destination space. (CVE-2026-53195)

Solution

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