[S] Change in libosmocore[master]: gb: fix buffer overflow in bssgp_rx_paging()
by laforge 10 Aug '26

10 Aug '26

laforge has submitted this change. ( https://gerrit.osmocom.org/c/libosmocore/+/43189?usp=email ) Change subject: gb: fix buffer overflow in bssgp_rx_paging() ...................................................................... gb: fix buffer overflow in bssgp_rx_paging() gsm48_parse_ra() was called against a local 6-byte buffer that was first memcpy()'d from TLVP_VAL() using the IE's own TLVP_LEN(), which can exceed 6 bytes for BSSGP_IE_LOCATION_AREA (5 bytes expected) and BSSGP_IE_ROUTEING_AREA (6 bytes expected) when a peer sends a larger IE, overflowing ra[]. Drop the intermediate copy and pass the TLV pointer directly to gsm48_parse_ra(), which only reads the bytes it needs.
