Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> io_uring: fix filename leak in __io_openat_prep()<br /> <br /> __io_openat_prep() allocates a struct filename using getname(). However,<br /> for the condition of the file being installed in the fixed file table as<br /> well as having O_CLOEXEC flag set, the function returns early. At that<br /> point, the request doesn&amp;#39;t have REQ_F_NEED_CLEANUP flag set. Due to this,<br /> the memory for the newly allocated struct filename is not cleaned up,<br /> causing a memory leak.<br /> <br /> Fix this by setting the REQ_F_NEED_CLEANUP for the request just after the<br /> successful getname() call, so that when the request is torn down, the<br /> filename will be cleaned up, along with other resources needing cleanup.
