CVE-2026-93090

A flaw was found in the Linux kernel's ARM System Control and Management Interface SCMI firmware. During the setup of SCMI channels, a failure can occur where previously registered resources are not properly released. This oversight can lead to resource exhaustion, potentially causing system...

Astra Linux – Vulnerability in Linux 5.15, Linux

In the Linux kernel, the following vulnerability has been resolved: Firmware: armscmi: Hardened access to reset domains. Accessing reset domain descriptors via indexes in SCMI driver requests, through the SCMI reset operation interface, may potentially lead to out-of-bound violations if the SCMI...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Firmware: armscmi: Balances the device reference count when destroying devices. Using devicefindchild to find the appropriate SCMI device to destroy causes an imbalance in the device reference count. This occurs because...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Firmware: armscmi: Fixed a double-free operation in the OPTEE transport. Channels can be shared between protocols; avoiding the need to free the same descriptor twice when unloading the stack...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Firmware: armscmi: Fixed a double-free in the SMC transport cleanup process. When the generic SCMI code destroys a channel, it calls the chanfree callback function, which is defined by each transport. Since multiple protocols may...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: The regulator: scmi – a fix was made to the refcount leak in scmiregulatorprobe. The offindnodebyname function returns a node pointer with the refcount incremented; we should use ofnodeput on it after processing. Add the missing...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: pmdomain: arm: scmi: Fixed the issue of a memory leak caused by the failure to remove generic power domains when the ofgenpdaddprovideronecell function fails during probing. If the ofgenpdaddprovideronecell function fails during...

AZL-101957 CVE-2026-93085 affecting package kernel for versions less than 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: firmware: armscmi: Reject out of range DT protocol IDs SCMI protocol IDs carried in message headers are limited by MSGPROTOCOLIDMASK. The DT parsing paths noticed protocol IDs outside that range, but only logged an error and then...

EUVD-2026-82194

In the Linux kernel, the following vulnerability has been resolved: firmware: armscmi: Drop handle on protocol bind failures The SCMI bus notifier acquires an SCMI handle when the driver core emits BUSNOTIFYBINDDRIVER, before invoking the protocol driver probe callback. The protocol probe path on...

PT-2026-94882
