## Machine-written summary

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

> The Linux kernel spi oc-tiny driver, from 2.6.39 onward, can access freed memory during driver removal if a late or latched interrupt arrives. The source gives few details on what an attacker needs or what they could gain. Upgrade to 6.1.191, 6.6.160, 6.12.110 or 6.18.52, or to later releases in those series.
