"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: ufs: core: Validate string descriptors\n\nThe string descriptor length includes a two-byte header while the UTF-16\npayload starts after it. utf16s_to_utf8s() expects a count of UTF-16 code\nunits, not bytes. Passing the payload byte count can make it read beyond\nthe descriptor buffer.\n\nValidate that the payload has an even byte count, pass a code-unit count to\nthe converter, and allocate sufficient UTF-8 output space.\n\nThe raw string buffer starts after the descriptor header but its size is\nbLength. Copying bLength bytes from that pointer can read beyond the\nresponse buffer.\n\nAllocate a zeroed bLength-sized buffer and copy only the UTF-16\npayload. This preserves the raw buffer size consumed by the RPMB device-ID\nABI while avoiding the overread."
