CVE-2022-50015:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2022-50015 affects the Linux kernel, specifically in the ASoC: SOF: Intel: hda-ipc component. The vulnerability was discovered and reported with IPC4 firmware, though the same condition exists for IPC3. The issue was publicly disclosed on June 18, 2025 (NVD).
Technical details
The vulnerability stems from improper validation in the firmware boot sequence. Specifically, it is possible to create a firmware configuration that sends a reply message before a FWREADY message. Since the replydata is allocated only after the FW_READY message, this sequence can lead to a NULL pointer dereference if not properly filtered (Wiz).
Impact
When exploited, this vulnerability can result in a NULL pointer dereference, potentially leading to system instability or denial of service conditions (Wiz).
Mitigation and workarounds
The vulnerability has been fixed in various Linux kernel versions. For Debian systems, fixes are available in version 6.1.137-1 for bookworm, 6.1.140-1 for bookworm (security), 6.12.31-1 for trixie (security), and 6.12.32-1 for sid and trixie releases (Debian Security).
