In the Linux kernel, the following vulnerability has been resolved: remoteproc: scp: Fix device reference leak on failed lookup Make sure to drop… (CVE-2026-89512)
A vulnerability in the Linux kernel's remoteproc SCP driver caused a device reference leak during failed driver data lookups. The issue involved not properly dropping the reference to the SCP device when the driver data was accessed before the driver was bound. This flaw could lead to resource leaks in the kernel.
AI Analysis
Technical Summary
The Linux kernel's remoteproc SCP driver had a vulnerability where a device reference was leaked if the lookup for the device's driver data failed. Specifically, the code did not release the reference taken on the SCP device when attempting to access its driver data before the driver was bound. This could cause a resource leak because holding a device reference does not guarantee the persistence of its driver data. The vulnerability has been resolved by ensuring the reference is properly dropped on failure.
Potential Impact
The vulnerability results in a device reference leak in the Linux kernel, which could lead to resource exhaustion or instability over time. There is no indication of direct code execution or privilege escalation from this issue. No known exploits in the wild have been reported.
Mitigation Recommendations
A fix has been applied to the Linux kernel to properly drop the device reference on failed lookups in the remoteproc SCP driver. Users should update to the fixed kernel version once available. No additional mitigation steps are indicated.
