CVE-2024-47746

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

fuse: use exclusive lock when FUSE_I_CACHE_IO_MODE is set

This may be a typo. The comment has said shared locks are not allowed when this bit is set. If using shared lock, the wait in `fuse_file_cached_io_open` may be forever.
