ModemManager patches CVE-2026-95622 cell-broadcast assert crash — Merged fix stops ModemManager from asserting and exiting when a cell broadcast uses unsupported 8-bit or reserved encodings, which a compromised base station or modem firmware could trigger (CVSS 6.5, CWE-617). gitlab.freedesktop.org · cmuuuew0fce901d4790077f18

Open5GS preserves AMF/MME RAN node IDs across SCTP association replacement — PR #4820 adds ogs_hash_set_rekey() so a gNB/eNB that reappears on a new SCTP association keeps its node-ID index; the previous remove-and-replace path could drop the mapping and hang N2 handover. github.com · cmuuuew0p99c36469b22bebab

Open5GS SMF tolerates late PDU setup responses during PFCP deletion — PR #4818 fixes a race where a queued PDU Session Resource Setup Response could hit the SMF after a session had already entered PFCP deletion following a rapid /modify then /release sequence from the AMF. github.com · cmuuuew1097136fa8b0061c05

Open5GS hardens NAS/MME/AMF/SGWC against malformed peer identities and PCO — A mainline commit now validates IMEISV, IMSI, SGsAP, and GTP PCO lengths before decode or copy, replacing reachable assertions and out-of-bounds paths on peer-controlled fields with safe rejects. github.com · cmuuuew1a36efe23f5a4f7315

libqmi adds Foxconn AP (0xE4) FCC unlock service for Lenovo WWAN modules — Merge request !473 introduces the FOXAP QMI service and a qmicli --foxap-set-fcc-authentication command for modules such as the Foxconn T99W696 (Qualcomm SDX61) that expect FCC unlock on service 0xE4 rather than the older FOX 0xE3 path. gitlab.freedesktop.org · cmuuuew1o5f1aa917ec548d90
