AI-suggested
A patch is available and should be applied. Ubuntu has released updated kernel packages that address this issue. After applying the update, a system reboot is required. Due to an ABI change, third-party kernel modules must be recompiled and reinstalled. Follow the vendor advisory instructions for updating to the fixed kernel versions.
Description
A vulnerability in the Linux kernel's ASoC SDCA component causes improper cleanup of IRQs, leading to potential crashes when IRQ handlers reference torn-down sound card components. This issue affects multiple linux-hwe-edge kernel versions prior to 7.0.0-1006.6. A patch is available to fix the problem by removing devm usage and implementing manual IRQ cleanup. The vulnerability has a CVSS score of 5.5, indicating medium severity, with impact limited to availability (denial of service).
