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." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "url": "https://github.com/sargun/fuse-example", "refsource": "MISC", "name": "https://github.com/sargun/fuse-example" }, { "url": "https://sourceforge.net/p/fuse/mailman/message/36598753/", "refsource": "MISC", "name": "https://sourceforge.net/p/fuse/mailman/message/36598753/" }, { "refsource": "CONFIRM", "name": "https://security.netapp.com/advisory/ntap-20200608-0001/", "url": "https://security.netapp.com/advisory/ntap-20200608-0001/" }, { "refsource": "MLIST", "name": "[oss-security] 20200824 CVE-2019-20794 kernel: task processes not being properly ended could lead to resource exhaustion", "url": "http://www.openwall.com/lists/oss-security/2020/08/24/1" } ] } }
