  "description": "In the Linux kernel, the following vulnerability has been resolved:  io_uring/kbuf: fix signedness in this_len calculation  When importing and using buffers, buf-\u003Elen is considered unsigned. However, buf-\u003Elen is converted to signed int when committing. This can lead to unexpected behavior if the buffer is large enough to be interpreted as a negative value. Make min_t calculation unsigned.",
