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...

Linux - Broken uid/gid 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 exceeds 5: Instead of linear search over an unsorted array of...

kernel: fuse-backed file mmap-ed onto process cmdline arguments causes denial of service

By mmaping a FUSE-backed file onto a process's memory containing command line arguments or environment strings, an attacker can cause utilities from psutils or procps such as ps, w or any other program which makes a read call to the /proc//cmdline or /proc//environ files to block indefinitely...
