# Memory corruption while maintaining memory maps of HLOS memory

A use-after-free memory corruption bug in DSP Services on multiple Qualcomm chipsets lets software corrupt memory used to map high-level OS memory. CISA reports it is being exploited in the wild.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Multiple Qualcomm chipsets contain a use-after-free vulnerability due to memory corruption in DSP Services while maintaining memory maps of HLOS memory.

CISA required action: Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.
