orangefs: keep the readdir entry size 64-bit in fill_from_part()<\/p>\n
fill_from_part() computes the size of a directory entry in size_t but
\nstores it in a __u32. An entry length near U32_MAX wraps it to a small
\nvalue, bypasses the bounds check, and is then used to index the entry,
\nreading far past the directory part — an out-of-bounds read that oopses
\nthe kernel.<\/p>\n
Compute the size as a u64 so it cannot truncate; the bounds check then
\nrejects the entry. The trailer is supplied by the userspace client.<\/p>\n","protected":false},"excerpt":{"rendered":"
