Descriptions

drivers/net/ethernet/xilinx/xilinx_emaclite.c in the Linux kernel before 5.13.3 makes it easier for attackers to defeat an ASLR protection mechanism because it prints a kernel pointer (i.e., the real IOMEM pointer).

El archivo drivers/net/ethernet/xilinx/xilinx_emaclite.c en el kernel de Linux versiones anteriores a 5.13.3, facilita a atacantes derrotar un mecanismo de protección ASLR porque imprime un puntero del kernel (es decir, el puntero real de IOMEM)

It was discovered that a race condition existed in the Atheros Ath9k WiFi driver in the Linux kernel. An attacker could possibly use this to expose sensitive information. Alois Wohlschlager discovered that the overlay file system in the Linux kernel did not restrict private clones in some situations. An attacker could use this to expose sensitive information. It was discovered that the KVM hypervisor implementation in the Linux kernel did not properly compute the access permissions for shadow pages in some situations. A local attacker could use this to cause a denial of service. Various other issues were also addressed.
