GHSA-G64M-M7R3-J854
Vulnerability from github – Published: 2024-04-17 12:32 – Updated: 2025-01-27 15:30
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Fix double free in SMC transport cleanup path
When the generic SCMI code tears down a channel, it calls the chan_free callback function, defined by each transport. Since multiple protocols might share the same transport_info member, chan_free() might want to clean up the same member multiple times within the given SCMI transport implementation. In this case, it is SMC transport. This will lead to a NULL pointer dereference at the second time:

| arm-scmi firmware:scmi: SCMI Notifications - Core Enabled.

Simply check for the struct pointer being NULL before trying to access its members, to avoid this situation.
This was found when a transport doesn't really work (for instance no SMC service), the probe routines then tries to clean up, and triggers a crash.

Mitigation
Architecture and Design
Choose a language that provides automatic memory management.
Mitigation
Implementation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
Mitigation
Implementation
Use a static analysis tool to find double free instances.
