Overview
What is CVE-2026-92491?
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Roll back partial protocol table registration
scmi_protocol_table_register() can leave earlier requests registered when a later entry in the same ID table fails. Each request retains a pointer to the driver's ID table, so a failed module load can leave a dangling pointer after the module storage is released.
Unrequest only the successfully registered prefix, in reverse order, before returning the failure. Leave the failed entry and the remaining entries untouched because matching requests can be owned by another driver.
