CVSS v3.1
7.8
High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.58
Description
A double free vulnerability in the OPTEE transport of the Linux kernel's firmware for ARM SCMI has been resolved. The issue occurred because channels can be shared between protocols, and the same channel descriptors were being freed twice when unloading the stack. This could allow an attacker to impact the confidentiality, integrity, and availability of protected information.
Recommendations
For Linux kernel versions prior to 6.6.58, update to version 6.6.58 or later to resolve the issue. As a temporary workaround, consider restricting access to the
scmi optee chan free() function in the drivers/firmware/arm scmi/optee.c module until a patch is available. Avoid using shared channels between protocols to minimize the risk of exploitation.Exploit
