UBUNTU-CVE-2026-98796

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtkethsoc: allocate dummy netdev sooner The RX rings and the shared NAPI are carried by an internal "dummy" netdev eth-dummydev. mtkprobe creates that dummy device, and adds the shared tx/rx NAPI to it, only after...

UBUNTU-CVE-2026-98812

In the Linux kernel, the following vulnerability has been resolved: net/mctp: publish the mctpdev only after it is initialised mctpadddev links the new mctpdev into dev-mctpptr before mdev-dev is assigned, so a reader that picks the device up in that window dereferences a netdevice pointer that i...
