      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbinfmt_misc: use exe_file_deny_write_access() for the interpreter clone\n\nFor MISC_FMT_OPEN_FILE entries load_misc_binary() clones the\nregistered interpreter file and denies write access to the clone via\nplain deny_write_access(). The clone is installed as\nbprm->interpreter and later released by the exec machinery through\nexe_file_allow_write_access() which skips the i_writecount increment\nfor files with FMODE_FSNOTIFY_HSM set.\n\nThe deny and allow side can therefore come to different conclusions\nwhen pre-content watches are in play: if a pre-content watch is added\nto the interpreter after registration every subsequent exec through\nthat entry takes a write denial on the clone that is never paired\nwith a write allowance, driving the interpreter inode's i_writecount\nfurther down with each exec and leaving the interpreter unwritable\neven after the entry and all its users are gone.\n\nTake the write denial via exe_file_deny_write_access() so both sides\nof the pairing base their decision on the same file mode, and\npropagate failure instead of silently ignoring it: an interpreter\nthat is concurrently open for writing now fails the exec with\nETXTBSY, exactly like an interpreter freshly opened via open_exec()\nwould.",
