Linux - Broken uidgid Mapping for Nested User Namespaces

Linux - Broken uidgid Mapping for Nested User Namespaces commit 6397fac4915a "userns: bump idmap limits to 340" increases the number of possible uid/gid mappings that a namespace can have from 5 to 340. This is implemented by switching to a different data structure if the number of mappings excee...

UBUNTU-CVE-2018-18955

In the Linux kernel 4.15.x through 4.19.x before 4.19.2, mapwrite in kernel/usernamespace.c allows privilege escalation because it mishandles nested user namespaces with more than 5 UID or GID ranges. A user who has CAPSYSADMIN in an affected user namespace can bypass access controls on resources...
