# Possible use after free when process shell memory is freed using IOCTL munmap call and process initialization is in…

Multiple Qualcomm chipsets have a use-after-free bug when process shell memory is freed through an IOCTL munmap call while process initialization is still running. A local attacker can use it to corrupt memory and likely gain elevated privileges on the device.

_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 when process shell memory is freed using IOCTL munmap call and process initialization is in progress.

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