Last modified

CVE-2026-93090 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Clean up channels on setup failure scmi_channels_setup() can fail after the common BASE channel or earlier protocol channels have already been registered in the TX/RX IDRs. Route this failure through the existing channel cleanup label so the transport channels, transport devices and IDR state created before the failure are released before the probe error path frees the SCMI instance ID.. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
