📋 Description
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_ffa: Bound PARTITION_INFO_GET_REGS copies
The register-based PARTITION_INFO_GET path trusted the firmware-provided indices when copying partition descriptors into the caller buffer. Reject inconsistent counts or index progressions so the copy loop cannot write past the allocated array.
(fixed cur_idx when exactly one descriptor in the first fragment)
