CVE-2026-53204

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A NULL pointer dereference occurs in the stratix10-rsu firmware component during the probe process. When the rsu send msg() function returns a timeout error (-ETIMEDOUT), certain error paths in the stratix10 rsu probe() function call stratix10 svc free channel(), which sets the chan->scl variable to NULL. However, the execution continues and queues a subsequent request on the same channel. This leads to a NULL pointer dereference when the service kernel thread accesses pdata->chan->scl in its receive callback path.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
