  "summary": "orangefs: fix double-free of trailer_buf on readdir copy failure",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\norangefs: fix double-free of trailer_buf on readdir copy failure\n\nOn a readdir downcall, orangefs_devreq_write_iter() frees\nop->downcall.trailer_buf with vfree() when copy_from_iter_full() fails,\nbut does not clear the pointer before goto Efault. The waiter in\ndo_readdir() is then woken with a negative status and frees the same\npointer again on its r < 0 path, causing a deterministic double-free.\nA client holding /dev/pvfs2-req triggers it by sending a readdir\ndowncall whose declared trailer_size exceeds the bytes it supplies.\n\nClear the pointer after freeing so the readdir-side vfree() becomes a\nno-op.",
