Memory corruption via remote procedure IOCTL calls
Published Oct 9, 2025 · Updated Oct 9, 2025
Out-of-bounds write in Qualcomm Snapdragon DSP service allows local users to corrupt memory through remote procedure IOCTL calls. Qualcomm identifies the locus as the DSP service but has not disclosed the specific buffer or bounds check that mishandles an IOCTL request. A low-privileged local user can trigger the flaw without interaction; Qualcomm has not stated whether exploitation causes a crash, code execution, or another outcome.
