Description (CNA)
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)
