Machine-written summary

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

The mmc via-sdmmc driver in the Linux kernel is affected from version 2.6.31 until fixed. After the device is removed, queued card-detect work can still run and access freed memory, and the source gives few details on what an attacker needs to trigger this. Upgrade to 5.10.273, 5.15.224, 6.1.191, 6.6.160, or a later release in those stable series.

Written 12 Nov 2026.
