Echo: linux: security update to 6.1.176-1

medium Tenable Self-Hosted Container Security Plugin ID 463160

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: HID: core: clamp report_size in
 s32ton() to avoid undefined shift s32ton() shifts by n-1 where n is the field's report_size, a value that
 comes directly from a HID device. The HID parser bounds report_size only to <= 256, so a broken HID device
 can supply a report descriptor with a wide field that triggers shift exponents up to 256 on a 32-bit type
 when an output report is built via hid_output_field() or hid_set_field(). Commit ec61b41918587 ("HID:
 core: fix shift-out-of-bounds in hid_report_raw_event") added the same n > 32 clamp to the function
 snto32(), but s32ton() was never given the same fix as I guess syzbot hadn't figured out how to fuzz a
 device the same way. Fix this up by just clamping the max value of n, just like snto32() does.
 (CVE-2026-31624)

Solution

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