BusyBox wget's FEATURE_WGET_TIMEOUT handler in networking/wget.c crashes with a null pointer dereference when the -T (timeout) argument is processed, affecting versions 1.30.0 and 1.30.1. Local users who can invoke BusyBox wget can trigger a denial-of-service crash of the wget process by supplying a crafted -T argument value, exploiting an unguarded pointer dereference in the shared getopt32 option-parsing library. No public exploit has confirmed active production exploitation, but a public proof-of-concept is available and the CVE is not listed in CISA KEV.
