## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> The Linux kernel remoteproc qcom_wcnss driver, used on pronto-v3 platforms, can move a pointer past the end of its array when a platform has no power domain regulators. The source gives few details on who can trigger this or what an attacker could gain. Upgrade to kernel 6.1.191, 6.6.160, 6.12.114, or 6.18.57 or later in the matching stable branch, or to a release that includes the fix.
