kernel: xen/privcmd: fix double free via VMA splitting

A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: bpf: Fixed a use-after-free in arenavmclose when processing forks. The arenavmopen function only increments vml-mmapcount, but never registers the child VMA in arena-vmalist. vml-vma always points to the parent VMA; therefore,...
