CVE-2025-37979: ASoC: qcom: Fix sc7280 lpass potential buffer overflow

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux a12c14577882b1f2b4cff0f86265682f16e97b0c, a31a4934b31faea76e735bab17e63d02fcd8e029, b807b7c81a6d066757a94af7b8fa5b6a37e4d0b3; azl3 kernel 6.6.85.1-4 on Azure Linux 3.0 6.6.92.2-1; azl3 kernel 6.6.92.2-1 on Azure Linux 3.0 6.6.92.2-1.

Low priority for now. Upgrade to Linux Linux a12c14577882b1f2b4cff0f86265682f16e97b0c, a31a4934b31faea76e735bab17e63d02fcd8e029, b807b7c81a6d066757a94af7b8fa5b6a37e4d0b3; azl3 kernel 6.6.85.1-4 on Azure Linux 3.0 6.6.92.2-1; azl3 kernel 6.6.92.2-1 on Azure Linux 3.0 6.6.92.2-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ASoC: qcom: Fix sc7280 lpass potential buffer overflow Case values introduced in commit 5f78e1fb7a3e ("ASoC: qcom: Add driver support for audioreach solution") cause out of bounds access in arrays of sc7280 driver data (e.g. in case of RX_CODEC_DMA_RX_0 in sc7280_snd_hw_params()). Redefine LPASS_MAX_PORTS to consider the maximum possible port id for q6dsp as sc7280 driver utilizes some of those values. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
