- Summary
- CVE-2025-68239 affecting package kernel 6.6.126.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
binfmtmisc: restore write access before closing files opened by openexec()
bmregisterwrite() opens an executable file using openexec(), which internally calls doopen_execat() and denies write access on the file to avoid modification while it is being executed.
However, when an error occurs, bmregisterwrite() closes the file using filp_close() directly. This does not restore the write permission, which may cause subsequent write operations on the same file to fail.
Fix this by calling exefileallowwriteaccess() before filp_close() to restore the write permission properly.
