"value": "In the Linux kernel, the following vulnerability has been resolved:\n\naccel/amdxdna: Remove __counted_by from struct amdxdna_cmd_chain\n\nstruct amdxdna_cmd_chain contains a flexible array annotated with\n__counted_by(command_count). Since the structure is stored in shared\nAMDXDNA_BO_SHARE memory, userspace can modify command_count concurrently.\nIf command_count is changed to zero, the bounds check generated from\n__counted_by may fail and trigger a kernel panic.\n\nRemove __counted_by to avoid relying on the userspace-controlled\ncommand_count for the flexible array bounds check."
