- Summary
- CVE-2025-68814 affecting package kernel for versions less than 6.6.121.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix filename leak in __ioopenatprep()
__ioopenatprep() allocates a struct filename using getname(). However, for the condition of the file being installed in the fixed file table as well as having OCLOEXEC flag set, the function returns early. At that point, the request doesn't have REQFNEEDCLEANUP flag set. Due to this, the memory for the newly allocated struct filename is not cleaned up, causing a memory leak.
Fix this by setting the REQFNEED_CLEANUP for the request just after the successful getname() call, so that when the request is torn down, the filename will be cleaned up, along with other resources needing cleanup.
