In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: avs: Disable periods-elapsed work when closing PCM… (CVE-2025-40344)
A vulnerability in the Linux kernel related to the ASoC Intel AVS driver has been resolved. The issue involves improper synchronization between the shutdown procedure of the HOST HDAudio stream and the period-elapsed work servicing its IRQs. This can lead to use-after-free errors, potentially causing severe impacts on confidentiality, integrity, and availability. The vulnerability is rated as high severity. No specific affected versions are provided. No known exploits are reported in the wild. No explicit patch or remediation details are included in the provided data.
AI Analysis
Technical Summary
The vulnerability (CVE-2025-40344) affects the Linux kernel's ASoC Intel AVS component. The function avs_dai_fe_shutdown() handles shutting down the HOST HDAudio stream while period-elapsed work continues servicing interrupts. Because the shutdown frees the DAI's private context, lack of synchronization between these operations can cause slab-use-after-free errors or worse. This can lead to high impact on system confidentiality, integrity, and availability as indicated by the CVSS vector. The issue has been resolved in the Linux kernel, but no explicit patch versions are provided.
Potential Impact
Exploitation of this vulnerability could result in use-after-free conditions, potentially allowing attackers with local privileges to cause system crashes or escalate privileges, impacting confidentiality, integrity, and availability of the affected system. The CVSS vector indicates high impact on all three security aspects. No known exploits in the wild have been reported.
Mitigation Recommendations
The vulnerability has been resolved in the Linux kernel. However, no explicit patch or fixed version information is provided in the available data. Users should monitor official Linux kernel advisories for the relevant patch and apply it once available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
