GHSA-CP9V-662Q-VVX9 Pillow: NULL pointer dereference in Image.merge via an unvalidated band 0

Summary Image.merge checks the mode of every input band except band 0. If band 0 is a single-band I or F image, the native merge routine reads a pixel pointer that is NULL for those modes and the process crashes. The IPTC plugin reaches this from a plain Image.open followed by a load, and IPTC ha...

CVE-2026-79976

The MCTP-over-I2C+GPIO target binding in subsys/pmci/mctp/mctpi2cgpiotarget.c emulates a small pseudo-register file, where the bus controller first writes a register number and then writes or reads payload bytes. The selected register b-regaddr and the data-phase flag b-rxtx were never cleared wh...

CVE-2026-79976

The MCTP-over-I2C+GPIO target binding in subsys/pmci/mctp/mctp_i2c_gpio_target.c is vulnerable to a NULL pointer dereference because the b->reg_addr and b->rxtx flags are not cleared when an I2C STOP is issued. This allows a controller on the shared management bus to re-enter mctp_i2c_gpio_...

CVE-2026-79976 NULL pointer dereference in the MCTP I2C+GPIO target binding triggerable by a peer I2C controller

The MCTP-over-I2C+GPIO target binding in subsys/pmci/mctp/mctpi2cgpiotarget.c emulates a small pseudo-register file, where the bus controller first writes a register number and then writes or reads payload bytes.
