Memory corruption via malformed IMS registration request
Published Jul 4, 2023 · Updated Aug 2, 2024
Memory corruption in Qualcomm Linux firmware allows local users with high privileges to corrupt memory through a crafted IMS registration request. The QcRilRequestImsRegisterMultiIdentityMessage handler corrupts memory while processing request data, but Qualcomm has not disclosed the faulty buffer operation. The documented gate is local, high-privilege access; Qualcomm has not specified whether successful exploitation crashes the component or executes code.
