CVE-2026-75892 Details
Description
In osmo-ggsn 1.14.0 an out of bounds write issue was found in the gtp_decode_pdp_ctx() function through the PDP context GSN-Address sub-field, leading to memory corruption.
A memory corruption vulnerability due to an out-of-bounds write has been identified in Osmo GGSN version 1.14.0. The issue arises in the gtp_decode_pdp_ctx() function, where the GSN-Address sub-field lengths of a PDP Context Information Element are copied into a fixed-size array without proper validation. This flaw allows a malicious or spoofed peer GSN to overflow the array by up to 239 bytes, corrupting adjacent memory structures. The vulnerability is present in the GTP decoder, which is also used by Osmo SGSN.
