CVE-2026-15461

The Sierra Wireless HL78xx modem GNSS driver drivers/modem/hl78xx/, later drivers/modem/vendorstandalone/hl78xx/ embeds a generic struct gnssnmea0183matchdata matchdata inside struct hl78xxgnssdata. The generic NMEA0183 match helper drivers/gnss/gnssnmea0183match.c requires that context to be the...

CVE-2026-15461

Zephyr RTOS HL78xx modem GNSS driver contains a type confusion caused by a struct member offset mismatch: struct gnss_nmea0183_match_data was placed as the second member instead of the first, so NMEA parse callbacks read and write state at a shifted offset. The GSV callback reads a bogus pointer ...

CVE-2026-71256 nanoMODBUS Client-Side Out-of-Bounds Read Leading to Wild-Pointer Write via object_id

nanoMODBUS through v1.23.0 contains an out-of-bounds stack read leading to a wild-pointer write in nmbsreaddeviceidentificationbasic / recvreaddeviceidentificationres in nanomodbus.c. A fixed 3-element stack array order3 = 0,1,2 maps object IDs to buffer indices. The server-supplied objectid fiel...
