- Summary
- io_uring/kbuf: fix signedness in this_len calculation
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
iouring/kbuf: fix signedness in thislen calculation
When importing and using buffers, buf->len is considered unsigned. However, buf->len 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.
