Noroxi assessment

Priority: This week (action score 63/100)

  • CISA has confirmed exploitation in the wild (Sep 15, 2022). Remediation deadline for US federal agencies: Oct 6, 2022.
  • Probability of exploitation in the next 30 days: 1.5% (FIRST EPSS); higher than 74.6% of all records.
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

Stack-based buffer overflow in the acdb_ioctl function in audio_acdb.c in the acdb audio driver for the Linux kernel 2.6.x and 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to gain privileges via an application that leverages /dev/msm_acdb access and provides a large size value in an ioctl argument.
