Una pérdida de memoria en la función komeda_wb_connector_add() en el archivo drivers/gpu/drm/arm/display/komeda/komeda_wb_connector.c en el kernel de Linux versiones anteriores a 5.3.8, permite a atacantes causar una denegación de servicio (consumo de memoria) mediante la activación de fallos de la función drm_writeback_connector_init() , también se conoce como CID-a0ecd6fdbf5d.

Jann Horn discovered that the OverlayFS and ShiftFS Drivers in the Linux kernel did not properly handle reference counting during memory mapping operations when used in conjunction with AUFS. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Nicolas Waisman discovered that the WiFi driver stack in the Linux kernel did not properly validate SSID lengths. A physically proximate attacker could use this to cause a denial of service. Various other issues were also addressed.
