CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's orangefs module, where the size of a directory entry is incorrectly stored as a 32-bit unsigned integer, leading to potential out-of-bounds reads. This flaw can cause kernel crashes when processing directory entries with sizes near the maximum limit, resulting in system instability. Linux administrators and developers using orangefs should prioritize addressing this vulnerability to prevent potential system failures.
Original NVD 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.
