Qualcomm Multiple Chipsets

CVE-2021-1905

Multiple Qualcomm Chipsets contain a use after free vulnerability due to improper handling of memory mapping of multiple processes simultaneously.

What this means for your business

  • It affects Qualcomm Multiple Chipsets. It matters if your company, or a supplier that handles your data, runs it.
  • Attackers are already using it. CISA added it to its list of flaws used in real attacks on 3 November 2021.
  • FIRST's prediction model gives it a 2% chance of attack attempts being seen in the next 30 days, ranking above 73% of all known flaws.

What to do

  1. 1Check whether your company or your suppliers run Qualcomm Multiple Chipsets.
  2. 2If you do, follow CISA's required action below. No patch reference has been published yet.
  3. 3Treat it as urgent. US federal agencies must fix it by 3 May 2022. That deadline does not apply to private companies, but it shows how seriously CISA takes it.
  4. 4Because attackers have used it, check the affected systems for signs of a break-in, not only for the update.
