Descriptions

In the Linux kernel, the following vulnerability has been resolved: efi: runtime: Fix potential overflow of soft-reserved region size md_size will have been narrowed if we have >= 4GB worth of pages in a
soft-reserved region.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: efi: runtime: corrige el posible desbordamiento del tamaño de la región reservada por software. md_size se habrá reducido si tenemos >= 4 GB de páginas en una región reservada por software.

A flaw was found in the Linux kernel. Due to an integer overflow, certain EFI-related memory reservations might receive a size other than expected, leading to a denial of service.

In the Linux kernel, the following vulnerability has been resolved: efi: runtime: Fix potential overflow of soft-reserved region size md_size will have been narrowed if we have >= 4GB worth of pages in a soft-reserved region.

It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the Atheros 802.11ac wireless driver did not properly validate certain data structures, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of service.
