The vulnerabilities of the functions rx_queue_add_kobject() and netdev_queue_add_kobject() (net/core/net-sysfs.c) in the Linux kernel allow attackers to compromise data integrity.

The vulnerability of the functions rxqueueaddkobject and netdevqueueaddkobject net/core/net-sysfs.c in the Linux kernel is related to errors in pointer counting in the networking subsystem. Exploiting this vulnerability could allow an attacker to compromise data integrity...

UBUNTU-CVE-2020-10781

A flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hotadd file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user...

kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c leads to denial of service

A flaw that allowed an attacker to leak kernel memory was found in the network subsystem where an attacker with permissions to create tun/tap devices can create a denial of service and panic the system...
