Descriptions
A flaw was found in the Linux kernel. A use-after-free vulnerability in the NFC stack can lead to a threat to confidentiality, integrity, and system availability.
Se ha encontrado un fallo en el kernel de Linux. Una vulnerabilidad de uso de memoria previamente liberada en la pila NFC puede conllevar a una amenaza a la confidencialidad, integridad y disponibilidad del sistema
It was discovered that the NFC subsystem in the Linux kernel contained a use-after-free vulnerability in its NFC Controller Interface implementation. A local attacker could possibly use this to cause a denial of service or execute arbitrary code. It was discovered that the SCTP protocol implementation in the Linux kernel did not properly verify VTAGs in some situations. A remote attacker could possibly use this to cause a denial of service. Various other issues were also addressed.
