xfs: validate attr entry pointer before field access
In the Linux kernel, the following vulnerability has been resolved: xfs: validate attr entry pointer before field access xfs_attr3_leaf_verify_entry() accesses lentry/rentry fields (namelen, valuelen) before checking if the entry pointer itself is within bounds. If nameidx is crafted to point near the end of the buffer, these field accesses can read out-of-bounds before the bounds check at name_end > buf_end is performed. Add explicit bounds checks for entry pointers before accessing their fields. Use offsetof() to check that the start of the flexible array member (nameval/name) is within bounds, which ensures all preceding fields are safe to access.
