Echo: linux: security update to 6.1.176-1

medium Tenable Self-Hosted Container Security Plugin ID 461951

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: ctxfi: Add fallback to default
 RSR for S/PDIF spdif_passthru_playback_get_resources() uses atc->pll_rate as the RSR for the MSR
 calculation loop. However, pll_rate is only updated in atc_pll_init() and not in hw_pll_init(), so it
 remains 0 after the card init. When spdif_passthru_playback_setup() skips atc_pll_init() for 32000 Hz,
 (rsr * desc.msr) always becomes 0, causing the loop to spin indefinitely. Add fallback to use atc->rsr
 when atc->pll_rate is 0. This reflects the hardware state, since hw_card_init() already configures the PLL
 to the default RSR. (CVE-2026-46049)

Solution

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