In the Linux kernel, the following vulnerability has been resolved: fsverity: reject FS_IOC_ENABLE_VERITY on mode 3 fds Commit 56124d6c87fd ("fsverity: support enabling with tree block size f_mode & FMODE_READ))' in __kernel_read() became reachable by fuzz tests. This happens if FS_IOC_ENABLE_VERITY is called on a fd opened with access mode 3, which means "ioctl access only". Arguably, FS_IOC_ENABLE_VERITY should work on ioctl-only fds. But ioctl-only fds are a weird Linux extension that is rarely used and that few people even know about. (The documentation for FS_IOC_ENABLE_VERITY even specif
