CVE-2022-50313

Summary: CVE-2022-50313 affects the Linux kernel (EROF S subsystem). The root cause is that the i_size field is signed; crafted negative i_size can be interpreted as a fast symlink, triggering an order = MAX_ORDER warning. The fix changes the handling to fall back to the generic path for such unu...
