CVE-2024-7537

Local information disclosure via SMS list overread

Published Aug 5, 2024 · Updated Aug 6, 2024

Out-of-bounds read in oFono 1.34 allows local users to disclose sensitive information through crafted QMI SMS message-list data. In get_msg_list_cb in drivers/qmimodem/sms.c, an untrusted message count drives array iteration and copying without checking that the returned list length contains that many entries. Exploitation requires local low-privileged access and a Qualcomm QMI modem; the disclosure alone does not execute code, but it can support a chain that runs as root.
