CVE-2022-22071· NVD / CVE Program· CNA qualcomm

Possible use after free when process shell memory is freed using IOCTL munmap call and process initialization is in progress in Snapdragon A

Noroxi assessment

Priority: This week (action score 61/100)

  • CISA has confirmed exploitation in the wild (Dec 5, 2023). Remediation deadline for US federal agencies: Dec 26, 2023.
  • Probability of exploitation in the next 30 days: 0.41% (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.
  • 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.

The score given by the assigning authority versus NVD’s independent score. A gap means the severity is contested.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Dec 5, 2023. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Dec 26, 2023.

Root cause

After a memory region is freed, another reference pointing to it is still used. By then, the same region may have been allocated for different data.
