Description
Description
In the Linux kernel, the following vulnerability has been resolved:
orangefs: keep the readdir entry size 64-bit in fill_from_part()
fill_from_part() computes the size of a directory entry in size_t but
stores it in a __u32. An entry length near U32_MAX wraps it to a small
value, bypasses the bounds check, and is then used to index the entry,
reading far past the directory part -- an out-of-bounds read that oopses
the kernel.
Compute the size as a u64 so it cannot truncate; the bounds check then
rejects the entry. The trailer is supplied by the userspace client.
