kernel: Count overflow in FUSE request leading to use-after-free issues.

A flaw was found in the Linux kernel's implementation of the FUSE filesystem, where it allows a page reference counter overflow. If a page reference counter overflows into a negative value, it can be placed back into the "free" list for reuse by other applications. This flaw allows a local attack...

An issue was discovered in the Linux kernel 4.18 through 5.6.11 when unprivileged user namespaces are allowed. A user can create their own PID namespace and mount a FUSE filesystem. Upon interaction with this FUSE filesystem if the userspace component is terminated via a kill of the PID namespace's pid 1 it will result in a hung task and resources being permanently locked up until system reboot. This can result in resource exhaustion.

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...
